Chelsea goalkeeper Thibaut Courtois could miss this weekend's fixture against Everton after picking up an ankle injury.
The Belgian came back unscathed from international duty but was hurt during a training session with the Chelsea squad on Wednesday.
The 23-year-old is set to have further tests before the early Saturday kickoff at Goodison Park, with Asmir Begovic ready to start should Courtois fail to recover in time.
Courtois has managed three appearances for the Premier League champions so far this season, conceding five goals.
