TJ Brodie will be out indefinitely for the Calgary Flames after the defenseman was released from a hospital Thursday.
The 29-year-old collapsed during a drill at practice, started convulsing, was removed on a stretcher, and was awake on the way to the hospital. He remained there for testing before he was released and spent the night at home with his family.
"TJ experienced an event on the ice early yesterday afternoon, about 15 minutes into practice," Flames general manager Brad Treliving said Friday. "He's feeling good. He's sore. All of the tests that have been done to date have come back negative. He's doing well ... we're not going to leave any stone unturned in terms of the tests that we go through."
Brodie has eight assists in 21 games this season for the Flames (10-8-3), who visit the Arizona Coyotes at Gila River Arena on Saturday (4 p.m. ET; FS-A, FS-A PLUS, SNF, NHL.TV).
"We're going to go through the process of checking every box and make sure we administer every test," Treliving said. "But he's come through everything thus far and doing well, feeling good. He's on the mend. He will obviously not travel with us today as we head to Arizona and Las Vegas. He will stay under the supervision of our medical team led by [Dr.] Ian [Auld]."
Auld said, "An event like this can be caused by something inside the brain, something scary, and it can also be caused by syncope or fainting episodes. The reasons for why people faint are many. I don't think we have all the answers yet, and we still have a few more tests to go, but all the early indications are that it's very likely more related to a fainting episode than something significant and inside the brain."
Flames captain Mark Giordano said the incident was unsettling but that he and his teammates were able to relax after visiting Brodie at the hospital.
"It was really reassuring to go to the hospital and see him back and acting normal and joking around," Giordano said. "I know it's happened before where guys have gone down and had episodes like that, but for me personally, seeing a teammate on the ice, I had never been a part of that.
"Knowing him for so long, playing with him his whole career and being really good friends, it was an emotional day. We all feel a lot better about things today with some positive news that he's home, he's resting, and he's feeling better. Hopefully he just keeps getting better and better and he's able to get back on the ice."
The Flames recalled defenseman Oliver Kylington from Stockton of the American Hockey League on Friday. He has one assist in 14 games with Calgary this season.
