Former England international Robinson started all 21 of Rovers' npower Championship matches before the weekend, when Kean was given the nod in a 2-0 defeat at Bloomfield Road
"It was a tight decision, a tough decision, because Paul has played every game," Berg told Rovers Player "At the same time we've not had the results we would have liked so I thought I would give Jake a chance this time.
"It was quite tight between the two of them so I thought it could have helped us a little bit. I couldn't complain about Jake for their goals.
"It was difficult for a goalkeeper, but I thought he did okay. They hardly had a shot on goal apart from the two goals they had.
"He made one good save from a free-kick and he came for one cross, but apart from that he wasn't troubled."
Blackburn have taken one point from their last five matches and have only one victory in nine since Berg was installed as Steve Kean's successor.
The Rovers faithful, having soundtracked much of Kean's reign with their clear disquiet, ensured the players felt their wrath on Saturday with chants of "you're not fit to wear the shirt" - something Berg believes was unhelpful
He was quoted in the Daily Star as saying: "These players don't get better from being booed or shouted at.
"To help the team and the players, the fans need to get right behind them. Push them and help them during the game and then let your frustrations out afterwards."
