Chelsea defender Jeffrey Bruma suffered a hamstring scare in their FA Youth Cup win over Nottingham Forest.
Bruma was taken off at halftime of the 4-0 win.
Blues coach Dermot Drummy told the club's website: "With Jeffery being a first-team squad player, we are grateful when we get him and as soon as we felt he might have a hamstring problem we took him off because if he went on and pulled it he could have been out two months."
Before last night's tie, he also said: "Jeffrey Bruma will be involved, he was fantastic in the last round for us, even in and around the hotel, he inspires the boys and they look up to him with his great attitude."
