An absolutely scary scene today at Calgary Flames practice. 

Defenseman T.J. Brodie collapsed on the ice and began convulsing. 

The defenseman was taken off the ice by paramedics and taken to the hospital in an ambulance. 

The Flames have relayed that Brodie was responsive and some have speculated he might have had a seizure. 

Practice was obviously canceled immediately and Flames' players were pretty rattled. 

More to come.
