"The Buffalo Sabres center was dealing with an ocular migraine throughout the 1-0 loss to Pittsburgh. It started just before the opening faceoff and caused vision problems and even some dizziness. On top of that, Roy was crushed in the left elbow by a Tyler Myers shoot-in during the first period that made his arm numb.

After all that, Roy took part in practice Thursday in a non-contact role in HSBC Arena. But he said he should be fine for tonight's visit from the Toronto Maple Leafs.

Roy, who has no history of headaches, said this one struck him during coach Lindy Ruff's pregame speech.

"I couldn't really see and it's tough to go out there when you can't see," Roy said. "The doctor said it might come back and it started to. It was the first time so it was kind of scary."

Roy said he felt better Thursday and the elbow was actually the bigger issue. Myers, who fractured the jaw of teammate Nathan Gerbe with a wayward shot earlier this month, was firing the puck into the Pittsburgh zone but it never got there.

"I saw him wind up so I slowed down because I was like, 'I'm right in his lane right now. This could be bad,'" Roy said with a pained smile. "He wound up and got a pretty good shot off. It was coming for my head so my first reaction was to put my arm up and it got me where there was no padding."

Roy said the arm went numb, much like a player's leg does when struck by a puck on the foot. Between the headaches and the elbow, Roy was in and out of the lineup. He played a season-low 15 minutes, 17 seconds."
