Tampa Bay Lightning defenseman Brendan Mikkelson was taken to Tampa General Hospital on Thursday after falling into the end boards during practice at the Forum.
Mikkelson, who left the building on a gurney, was later released from the hospital, according to the team. He is listed as day-to-day with an upper-body injury.
Midway through practice, Mikkelson was heading toward the goal at nearly full speed when he appeared to lose an edge or catch a rut in the ice, knocking him off balance. The back of his head and neck area slammed into the boards with a loud thud. Mikkelson briefly lost consciousness, prompting a quick response from team medical staff.
After lying on the ice for several nervous moments, Mikkelson moved all his extremities before being helped up on his skates. He walked to the locker room under his own power, but looked dazed.
"That was really scary and I'm not even totally sure what happened, whether our skates got caught up or he hit a rut, but we were both going full speed and I was right there when it happened,'' center Steven Stamkos said. "It looked like he didn't know where he was and was out of it for a bit. It was a big relief when he came to and was moving everything.''
