The Maple Leafs have assigned forward Matt Frattin and defenseman Korbinian Holzer to the AHL. Frattin appeared in 37 games for the Leafs this season, with five goals and 10 points. Holzer hasn't played in the NHL this season despite being called up on two occasions. The moves came with forward Mike Brown (lower body) and defenseman Mike Komisarek (broken arm) expected back from injury for Saturday's game against Detroit.
