Calgary Flames defenseman TJ Brodie collapsed and appeared to have a seizure on the ice during the team's practice on Thursday, according to Jermain Franklin of TSN:

According to the team, he was hospitalized and was "alert and responsive" following the episode:

The team later announced Brodie was discharged from the hospital.

On Friday, Flames general manager Brad Treliving told reporters all tests on Brodie had come back negative, but he noted there was no timeline for his return. 

According to Kristen Anderson of the Calgary Sun, Brodie "was standing by himself during a drill at the blueline when he suddenly fell to the ice and began convulsing." The good news, however, was that he "appeared to be moving his extremities and talking" when paramedics arrived.

Teammates and staff gathered around Brodie following his collapse to the ice:

According to ESPN, the team cancelled the remainder of practice following the incident.

Brodie, 29, has appeared in all 21 games for Calgary this season, registering eight assists while averaging 19 minutes, 13 seconds of ice time. He's been a regular fixture for the team in his 10-year career after being a fourth-round selection in the 2008 NHL draft, playing in 70 or more games the past six seasons. 

The Flames are 10-8-3 and in fourth place in the Pacific Division with 23 points.
