According to London Football Network, Chelsea winger Gittens was suspected of being injured when he represented England U21 against Ireland and is doubtful for Slovakia. In this game, Gittens stood up after falling to the ground in the opponent's penalty area, but he was obviously limping and appeared to be in some discomfort.

Gittens has been a member of Chelsea's squad for every game so far this season, missing only three games. The last time he played a full game was against Wolves in the fourth round of the Carabao Cup last month, assisting the first two goals and scoring the winning goal to help the team win 4-3.

If Gittens is indeed injured, this will be another blow to Chelsea's wide players. Pedro Neto has withdrawn from the Portugal national team and remains at Chelsea due to a groin problem. Palmer is also not expected to return when the league resumes next week. Mudrick remains suspended for a positive doping test last year. If Gittens is out, Garnacho will likely remain the starter.
