N'Golo Kante could be ruled out of the 2022 World Cup in Qatar after relapsing from his hamstring injury, according to reports.
Kante sustained the injury during Chelsea's draw with Tottenham in August. He was substituted in the 84th minute and replaced by Conor Gallagher.
The 31-year-old underwent regular rehab sessions with the club's medical staff and returned to training at Cobham at the end of September after missing six matches.
However, the French midfielder did not travel to Italy on Monday ahead of Chelsea's Champions League fixtures against AC Milan.
