Bowyer believes that newly-promoted Doncaster will play in the way their manager Paul Dickov did when he was a player.
Dickov was always a fans favourite for his wholehearted displays during his time at Ewood, and the Rovers boss feels that Dickov's Donny will be just as competitive.
"I was the youth team coach and I had to take one Reserve game when Dickov was playing in it so I've known him a long time," said Bowyer.
"Obviously he's got his connections with his club, we saw how he played and how he went about the game and I'm expecting his team to be exactly the same.
"I know that he'll want his teams to be as competitive as the way he played, so we are in for a tough night."
