Swansea City manager Michael Laudrup is hoping the ankle injury sustained by star goalscorer Michu is not too grave.
The Spaniard, who co-tops the Premier League scoring charts with 13 goals, came off late in the 0-0 draw with Reading on Wednesday and Laudrup now fears he may be sidelined for a little while.
"His ankle is twice as big now. We don't know how bad it is," Laudrup said.
"The doctors and the physios say it shouldn't be the ligaments, which is the most important thing.
"The next question is 'will he play on Saturday?' I don't know. We will have to wait 24 hours.
"Hopefully it is not too bad. It is not a muscle injury but still we have to be careful. He has to be 100 per cent.
"He is one of the top scorers in the league, definitely our top scorer. He has played nearly every match this season.
"Even if he is the most important player, we have to deal with it (if he is out). If you rely so much on one or two players it is not good for any team."
