Richard Dunne has suffered an injury scare ahead of Aston Villa's FA Cup semi-final clash with Chelsea.
The 30-year-old was forced to withdraw from a warm-up session on Thursday with a sore Achilles.
Dunne has been playing through the injury in recent weeks and will now face a late fitness test to determine whether he can do so again on Saturday.
Villa boss Martin O'Neill believes he still has every chance of featuring.
"Dunne has had a bit of a setback and he came out of training this morning," he said.
"He was a bit sore. It is an injury we have to be nursing through. It has been troublesome for a while but he definitely will want to play."
Midfielder James Milner has resumed training having recovered from a similar Achilles problem.
