Mikael Tam of the Quebec Remparts has been released from hospital after taking an elbow to the head from Rouyn-Noranda centre Patrice Cormier, who's now being investigated by police.

Tam went into convulsions and was taken to hospital after the hit, which occurred at 3:32 of overtime in Quebec's 3-2 shootout victory Sunday afternoon.

The Quebec Major Junior Hockey League has suspended Cormier indefinitely. Criminal charges may also be laid against him.

Remparts spokesman Nicole Bouchard said Tam suffered brain trauma and some damage to his teeth.

Brain scan

She said a brain scan was taken after the game, and a second scan Monday showed "everything normal."

The Remparts website is asking fans to send get well messages to the 18-year-old defenceman.

Police on scene

Quebec provincial police questioned witnesses at the rink after the game. Police spokesman Marie-Josee Ouellet said the incident is under investigation to see if there are grounds for criminal charges.

Video of the incident shows Cormier coming off the bench and heading towards Tam, who started his rush from behind the goal. Cormier caught him with the elbow near centre ice, dropping him.

Three players and a trainer rushed Tam off the ice on a stretcher.

Cormier is known as a physical player. He hammered Sweden's Anton Rodin with a similar elbow to the face during an exhibition game ahead of the world juniors last month.

The 19-year-old from Cap-Pele, N.B., was drafted by New Jersey in the second round in 2008 and signed a three-year entry level contract with the Devils last summer. He was traded by the Rimouski Oceanic to Rouyn-Noranda on Jan. 7.
