Chelsea boss Andre Villas-Boas has said that he is unsure of John Terry's fitness ahead of the Champions League tie against Napoli.
The captain's last appearance for his side was in the FA Cup fourth-round 1-0 win over QPR at the end of January.
He returned to training on Thursday but was left out of the 1-1 draw with Birmingham in the FA Cup fifth round today.
"We will have to wait and see [if he is fit]. At moment there is a 50-50 chance of him making it," the Portuguese manager told ESPN.
"He's going to train on Monday and travel with the team. After that we'll make a decision."
The former England captain has made 27 appearances for Chelsea so far this season.
