London: Chelsea captain John Terry will miss the club's Premier League clash with Swansea City on Tuesday because of a knee injury he picked up in the third-round FA Cup clash against Portsmouth.
The England international has been suffering from fluid in his knee joint after colliding with the goal-post while clearing the ball off the line, and despite playing through the pain in recent weeks, he will now miss the game against Premier League newcomers Swansea.
"It's just a bone oedema that he has been carrying for some time since he collided with a post, and this stops him a little bit," Chelsea manager Andre Villas-Boas told Chelsea TV.
"It's nothing serious but something to keep an eye on. He has had an MRI before and he should be okay for [Sunday's game against] Manchester United."
The news creates an opportunity for new signing Gary Cahill to make his first appearance for the club since his £7-million move to Stamford Bridge from Bolton.
"We have a lot of positions covered of course, because of our squad - We have Gary [Cahill] and David [Luiz] available and competing and hopefully we can make the right decision."
Villas-Boas also spoke of other absentees, including Frank Lampard, John Ob-Mikel and Ramires, who suffered medial ligament damage during Saturday's 1-0 victory over QPR in the fourth round of the FA Cup.
"It's unfortunate for the team; Rami is one of the most used players on the team with excellent individual performances and always helping the team to get results," Villas-Boas said.
"With what could have happened, it's just good news that he will be out for a short amount of time. Hopefully he will be available for the Napoli game [in the Champions League], and hopefully before."
"On another front, Mikel will be out of the game and Lamps still out. Frank's rehabilitation is going well, we are trying to reintroduce him gradually to the first-team activities."
"Frank felt that it was still a little bit soon to come back and went on to work with the physios, so hopefully after Swansea we will get him ready for the Man United game."
