The Rovers striker was a surprise absentee from the 18-man squad at the John Smith's Stadium, but Berg confirmed he had picked up a strain in training for the game.
"It won't be a long term with him but it is with the muscle so you don't know how long they are going to be," said Berg.
"We'll just have to wait and see, of course we want all our players back competing for a place in the team."
