Flames defenseman TJ Brodie was taken to the hospital Thursday after collapsing to the ice and convulsing during practice.

Reporters on the scene said practice came to a halt when Brodie fell in what was described as a “terrifying moment” by Kristen Anderson of the Calgary Sun. Multiple reporters said it appeared Brodie was having a seizure.

“TJ Brodie experienced an episode on ice at practice today. He is alert and responsive and has been transported to local area hospital for evaluation. We will provide a further update when available. Thank you,” Flames GM Brad Treliving said in a statement.

Brodie, 29, is in his ninth full season with the Flames and has registered eight assists through 21 games this season.
