Mark Hughes rates Andrew Johnson as unlikely to be fit for Saturday's FA Cup tie against Peterborough after suffering a minor hamstring tear.
Johnson was withdrawn from Fulham's 3-0 victory over West Brom as a precaution and Hughes is anxious not to take any risks with his injury-plagued striker.
"We have to be careful with Andy," Hughes said.
"He has had games in close succession, he had tightness in his hamstring and was a little sore on Monday. We took him for a scan and it came back that he had a grade one tear.
"At a push he could have played but if he had torn it completely it would be a five, six week injury and we couldn't afford that. "It's usually eight to 10 days for a grade one."
Fulham, for once, managed to find goals from elsewhere to make light of Johnson's absence up front. Simon Davies put the Cottagers ahead before Clint Dempsey and Brede Hangeland scored from corners.
"I am pleased. That's two wins in three games," Hughes said.
"Goals change games and we have struggled in that respect but we got a good goal before half-time which settled us and we went away from them in the end.
"Draws will give you some comforts in terms of how you perform but that doesn't move you up the league - three points and wins do.
"They have unfortunately been lacking in recent weeks. We have addressed that somewhat."
Fulham's victory lifted them six places and out of the relegation zone - but West Brom's slump continued. A fifth straight defeat is their worst run of results in six years.
Baggies manager Roberto di Matteo admitted his injury-depleted defence could not cope with Fulham's aerial prowess.
"We knew we were up against a big side today and we are missing five centre-halves and we don't quite have the resources to put an 11 out that could handle Fulham," he said.
"They were bigger than us and they took advantage of it.
"We have been OK on corners and set piece but in the last three games we have conceded and that is creeping in a bit."
Scott Carson failed to deal with Davies drive and that goal, just before half-time, set Fulham on the road to victory.
"Scott is disappointed. He probably could have done better. He knows that. He is big enough to know that," said Di Matteo.
"Everybody's mood is a little bit down at the moment. We have had a bad run. We are a little bit down but we have to keep going, we have to pick ourselves up.
"There are a lot of clubs fighting relegation. As a newly promoted club we knew we'd be in for a tough season. We are trying to give ourselves the best chance."Reuse content
