Antonelli Ill Before Mexico Title Decider: Vesti on Standby, Bottas Also Out and Friday Times

The biggest weekend in Kimi Antonelli's motor racing life so far began in silence. Instead of attending news conferences at the Autodromo Hermanos Rodriguez on Thursday, the 20 year old Italian was left to rest and recover, after Mercedes confirmed he was feeling under the weather with a viral illness. The FIA excused him from his mandatory media duties as a precaution, to give him the chance to rest ahead of the weekend. Mercedes said, in a statement reported by Sky Sports F1 and AFP on Friday: "We expect him to be back tomorrow."

That is the key sentence for fans. Neither Mercedes nor Cadillac, whose driver Valtteri Bottas also missed media day through illness, has announced a withdrawal from the Grand Prix. Both teams describe the absences as precautionary, and both expect their drivers back for Friday practice. The illness is still a story, though, because of what is at stake on Sunday. Antonelli can win the Formula 1 drivers title in Mexico, and he can do it by finishing ninth or higher, or even by scoring no points, provided neither George Russell nor Lewis Hamilton wins the race.

How ill is Antonelli, and what happens if he cannot race?

Mercedes has not given a detailed medical update beyond "viral illness" and "feeling under the weather". That is normal for a team protecting a driver before a title decider, but it leaves one question unanswered: what happens if Antonelli is still ill on Sunday? AFP reporting on Friday says that if Antonelli is too ill to race, his seat is likely to go to Mercedes reserve driver Frederik Vesti, who would make his Formula 1 racing debut after taking part in six free practice sessions for the team.

Vesti is already in Mexico for Friday practice, but in a different role. Mercedes team chief Toto Wolff said Vesti will take over George Russell's car in opening practice, as part of the rookie FP1 programme. That is separate from a race stand in, and fans should not confuse the two jobs. Vesti in FP1 for Russell is planned. Vesti in the race for Antonelli would only happen if Antonelli cannot race, and Mercedes has not announced that.

The title maths also changes if Antonelli misses the race, although not in the way many fans assume. If Antonelli scores no points, he still wins the title provided neither Russell nor Hamilton wins. Only a Russell win or a Hamilton win, combined with Antonelli scoring one point or fewer, sends the championship on to Sao Paulo on 6 to 8 November. A Vesti debut, in other words, would not automatically end Antonelli's title hopes, because Russell and Hamilton would still need to win the race. It would, however, make the weekend far harder for Mercedes, and it would deny Antonelli the chance to clinch the title in style, which is what he said he wants to do.

Antonelli himself struck a calm note before the illness news. In comments reported by LaPresse on Friday, he said: "I am really excited. I would love to clinch the title in style, with a great result. That is the mindset. It has always been that mindset, and it will remain so from now until the end of the season. I will simply try to enjoy every moment, because these are moments that will stay with me forever." He also plans to keep his permanent race number 12 if he wins the title, rather than switching to number 1.

Who else missed media day, and who replaces whom in FP1?

Bottas, 36, missed Thursday media day as he was unwell, according to Cadillac. The team said it had taken the decision to allow him a day of rest, to support his recovery, and that this is a precautionary measure and does not currently affect his participation in the remainder of the race weekend. Cadillac's reserve is Zhou Guanyu, who raced for Sauber from 2021 to 2024, and American Colton Herta is also available. Herta is scheduled to run in opening practice for Cadillac on Friday as the team builds up his mileage and assesses him as a potential replacement for Bottas next year.

Friday practice also features rookie outings across the grid, because FIA rules require each team to run a rookie driver in at least two FP1 sessions per car during the season. According to Friday reporting, Red Bull will field Ayumu Iwasa in place of Max Verstappen for FP1, Mercedes will see Vesti take over Russell's car, and McLaren's Lando Norris will be replaced by Leonardo Fornaroli for the session. Those are planned FP1 swaps, not illness replacements, and the regular drivers return for FP2.

That distinction matters for Antonelli. He is not a planned FP1 rookie swap. He is the championship leader, 123 points clear of Russell and 124 clear of Hamilton, with 125 points still available after Mexico. Mercedes expects him back for FP1 and FP2 on Friday. If he is not in the car on Friday, that will be the first real signal that Sunday is in doubt. Until then, the team message is rest, recover, and return.

What is the title maths for Sunday?

Antonelli arrives in Mexico with 365 points, Russell has 242, Hamilton has 241, Verstappen has 236, Leclerc has 233, and Norris has 211. Antonelli would become the youngest world champion in Formula 1 history at 20 years and 68 days on race day, beating Sebastian Vettel's record of 23 years and 134 days, and he would become Italy's first world champion since Alberto Ascari in 1953. He has won nine races this season, a total nobody else can equal.

The permutations, published by Reuters on 28 October and repeated in Friday reporting, are simple. Antonelli is champion on Sunday if he finishes in the top nine, which scores at least two points. If he finishes tenth, the title is still done provided Russell does not win. If Antonelli scores no points at all, he is still champion provided neither Russell nor Hamilton wins. Only a Russell win or a Hamilton win, combined with Antonelli scoring one point or fewer, sends the championship to Sao Paulo.

The constructors championship is a different story. Mercedes lead with 607 points, Ferrari have 474, and Red Bull and McLaren are tied on 355 points. Mercedes could clinch the constructors title in Mexico, but AFP reporting describes that as a long shot that needs a perfect Mercedes afternoon and a terrible Ferrari afternoon. Brazil the following weekend looks much more likely for the team title. LaPresse notes that Mercedes could clinch the constructors title for the first time since 2021, but only with a substantial haul of points from Antonelli and Russell combined with a disastrous race for Ferrari.

When is the Mexico City Grand Prix and how can I watch it?

The Mexico City Grand Prix weekend runs from Friday 30 October to Sunday 1 November, with no sprint race. The race is 71 laps of the 4.304 kilometre Autodromo Hermanos Rodriguez, a total distance of 305.584 kilometres, at about 2,200 metres above sea level. The thin air means less downforce and less cooling, so teams run Monaco level downforce packages and still reach Monza style top speeds on the long main straight.

Session times below are session start times, in London time first, then converted for Berlin and Paris, New York, Los Angeles and Karachi. Note the clock change trap: the United States leaves daylight time on Sunday morning, so New York moves from EDT to EST between qualifying and the race, while Europe is already on winter time.

| Session | Mexico City local | London GMT | Berlin and Paris CET | New York | Karachi PKT | | Practice 1, Friday 30 October | 12:30 | 18:30 | 19:30 | 14:30 EDT | 23:30 | | Practice 2, Friday 30 October | 16:00 | 22:00 | 23:00 | 18:00 EDT | 03:00 Saturday | | Practice 3, Saturday 31 October | 11:30 | 17:30 | 18:30 | 13:30 EDT | 22:30 | | Qualifying, Saturday 31 October | 15:00 | 21:00 | 22:00 | 17:00 EDT | 02:00 Sunday | | Race, Sunday 1 November, 71 laps | 14:00 | 20:00 | 21:00 | 15:00 EST | 01:00 Monday |

In the UK, every session is live on Sky Sports F1 and Sky Sports Main Event, with highlights on Channel 4 after the race. In the United States, the weekend is exclusive to Apple TV, which now carries Formula 1 in a new F1 channel on the platform, with F1 TV Premium included. In Mexico, Televisa carries the race on free to air television and on pay television via Sky Sports on izzi and Sky Plus. In Canada, TSN carries the race.

Why is Perez 300th race still a big story this weekend?

Sergio Perez starts his 300th Grand Prix on Sunday, at home, for Cadillac, fresh from a contract extension that will keep him at Cadillac through to 2029. On Wednesday he drove a show run on Paseo de la Reforma in Mexico City, in front of thousands of fans. Perez, 36, missed the 2025 season after leaving Red Bull at the end of 2024, and Cadillac are still the only team without a point after 18 races. His best home finish remains third in 2021, and he finished 19th at Austin.

Perez will become only the seventh driver in history to reach 300 race starts, and he gets to do it in front of his home crowd in Mexico City, on the weekend of the Day of the Dead celebrations. Even if Cadillac cannot fight for points, Perez will get a reception on Sunday that no other driver on the grid will match. For Antonelli, a Verstappen, Leclerc or Norris win crowns him anyway, as long as he scores at least a point or finishes ninth or better. That is why Mexico is the weekend where the championship stops being a maths problem and becomes a moment, provided the illness that kept Antonelli out of media day does not keep him out of the car as well.
