Aston Villa manager Gerard Houllier hopes that striker Gabriel Agbonlahor will be fit for Sunday's Midlands derby against Wolves.
The forward hobbled off in the early stages of Villa's Carling Cup victory over Blackburn on Wednesday night with calf problems.
But Agbonlahor suffered from a similar injury earlier in the season against Rapid Vienna but he was able to quickly shake off the complaint.
Houllier, who only recently took charge of Villa, is therefore optimistic that the 23-year-old will again be able to make a swift recovery.
He said: "Will Agbonlahor be fit for Sunday? I don't know. I'll tell you today or tomorrow.
"The most reassuring thing he said was that it is the two calves that he felt at the same time.
Cramp or fatigue
"If it is one calf, you might think it is a possible tear but it is the two calves so probably it involves cramp or fatigue.
"Gabby said that he had that during the home Europa League game with Rapid Vienna and then could play the following game."
Agbonlahor missed the first three games of the campaign with a calf problem.
Central defender Ciaran Clark suffered a dead leg against Blackburn although he would be unlikely to start against Wolves with the rested James Collins set to return.
Houllier said: "It's a dead leg, exactly what Stephen Ireland had on Tuesday in training. I am collecting them at the moment!
"It is a good sign because it shows we train as we play."
