The German has been discussing the Leeds forward and midfielder.
The Whites lost 2-0 to Birmingham City at Elland Road, with Wood enduring a quiet afternoon up front and Mowatt not offering much in the way of creativity from midfield.
But Rosler has given a reason for the displays of both.
The German told BBC Radio Leeds: "I think you could see today that Chris has not been on the training pitch for two weeks.
"I think there was not much space between the lines for Alex Mowatt. We felt the threat should come from wide areas, especially down the right."
Wood's isolation up front certainly suggests the 23-year-old had reason for his quiet performance.
The responsibility there, though, lies with boss Rosler to get Leeds playing in a way to involve the striker more, regardless of his fitness.
The German has been urged to play two up front before, especially with Mirco Antenucci making a big impact so far this season.
As for Mowatt, though, his form simply hasn't been the same this term, barring a couple of performances as an impact substitute. Is Rosler at fault for not getting the best out of the Leeds youngster, or should he be firmer with him in terms of criticising his displays?
