If any other part of Tomas Kaberle's body had of been injured, he would have made his return to the Maple Leafs lineup on Tuesday night. But concussions are handled with more caution. The Maple Leafs decided to exercise caution with Kaberle and sat him out for an eighth straight game on Tuesday night. "Almost any other injury, when you get to that point where a player feels that he can play, there's enough grey area where you let a guy go," coach Paul Maurice said after the morning skate. "But there is no grey area with a concussion. "And that's the way it should be." Kaberle expects to make his return on Friday night, when the Leafs visit the Sabres.
