Rene Meulensteen: "Unfortunately he kicked a ball wrongly in training which aggravated something in his groin as far as I'm aware.
"So we had a good look at it, we assessed him, and actually assessed him this morning as well.
"And unfortunately he was too big of a risk. With all the games coming up I didn't want to take the risk of having to start Berbatov in that position and maybe him have to come off and then you lose him for the other games."
Meulensteen said Fulham continued their trend of praiseworthy hard graft without reward.
He said: "It's the same story as the Spurs and Everton games.
"The goals that we concede, from set plays, it's not good enough defending, especially the one just before half time.
"I was hoping the experience would kick in a bit from some of these players, to steady the ship."
