Berg made the 'footballing decision' as he felt that Kean deserved the chance to play at Bloomfield Road, even though Rovers ended up on the reverse of a 2-0 score line.
Rovers results had not been the cleverest of late but they could have been a lot worse had it not been for some great saves from Robinson.
But at the moment, Berg is in charge and he told BBC Radio Lancashire: "It was purely a football decision. It was a tight decision and a difficult one to make.
"Jake has not played much but I've seen him in training and, with the results we've had lately, I felt that we should give him a chance."
