Toronto Maple Leafs forward Colby Armstrong is out indefinitely with a concussion, one he suffered Saturday against the Vancouver Canucks but didn't make the team aware of until Monday.
"It took us all by complete shock because we had no idea that he had his bell rung the other night," Leafs coach Ron Wilson said Monday night after a 3-2 shootout loss to Los Angeles. "He kind of kept that from us."
Armstrong had planned to play in Monday's game, but he told the team's training staff that afternoon he was feeling nauseous.
Wilson explained how the concussion happened to reporters.
"In the game the other night, (Armstrong) hit Ryan Kesler and actually he cracked his toe, but that wasn't an issue," Wilson said. "He didn't tell the trainers or the doctors (Sunday) that he had his bell rung. (Monday afternoon) he was nauseated, blurry vision, so he's got a concussion and we didn't know that until later in the afternoon.
"He's going to be out however long he needs to be out now."
Armstrong has only played in nine games this season due to an ankle sprain. He has one assist.
