Chelsea boss Jose Mourinho is hopeful that Thibaut Courtois's finger injury is not serious.
Speaking to reporters ahead of Chelsea's FA Cup tie against Watford on Sunday, the Chelsea manager said the club is yet to determine just how bad the problem is, and Mourinho is not sure whether it's broken.
If required, Mourinho has the luxury of calling on one of the Premier League's best goalkeepers in Petr Cech as a back-up.
Courtois picked up the injury on his right hand during the 5-3 defeat to Tottenham at White Hart Lane on Thursday. He appeared to hit his hand in a collision with a Chelsea teammate when attempting to throw the ball downfield.
"He [Courtois] has a problem in one of his fingers," Mourinho said. "Let's see what happens. I don't know [if it's broken]. I didn't ask. I just asked if he could carry on at half-time [at Tottenham]."

It was likely that Mourinho would have rotated Cech in for Courtois against the Hornets anyway, but this injury means it's almost certain that the Belgian international will be rested.
It remains to be seen whether he'll be fit to face Newcastle at Stamford Bridge the following weekend.
Courtois, who replaced Cech in the starting lineup over the summer, has made 19 appearances for Chelsea so far this season and has impressed Blues fans.
The defeat to Spurs was just Chelsea's second Premier League loss of the season so far, and they remain top of the table level on points with Manchester City.
Courtois, despite the five goals conceded against Tottenham, has been one of the best goalkeepers in the Premier League. It's a close run thing when debating whether Courtois is better than Manchester United stopper David De Gea, as the two young keepers are now generally viewed as the top two in England.
