Rovers were left without a Christmas home game when the referee deemed the Ewood Park pitch unplayable for the game against Brighton at the weekend and now the manager wants to see that freshness when Rovers travel to the Riverside.
"These fixtures are important because the games come thick and fast," Berg told Radio Rovers.
"There are a lot of games, maybe not for us because of the Brighton game being called off when we really wanted to play that.
"At the same time we look forward to the Middlesbrough game now, there'll be no fatigue for us now but we have to make sure that we are fresh, that we are 100% and look to make the most from that game."
"It is another tough away game for us. We have had some tough fixtures in the last month or so, we just have to make sure that we are prepared, have the right commitment, that we have the right attitude, that we take our chances when we get them and of course defend a little bit better in the box when we have to.
"After the last couple of games we need to sharpen up in terms of defending in our own box."
Tickets for the game will be on sale on the day at the Riverside, cash only from the visitors ticket office next to the away turnstiles. Prices are £27 for Adults, £17 for Seniors and £14 for Under 18s.
