According to the Associated Press, Kozari was able to move his arms before he was lifted off the ice.

The NHL said in a statement after the game that Kozari “was transported to UPMC Mercy Hospital for precautionary reasons” and that he is “conscious and alert, has use of all extremities and is expected to make a full recovery.”

“It was hard to watch,” Tampa Bay coach John Cooper said, according to the Associated Press, after his team’s 5-4 loss. “but [Fleury]I went to the locker room during that pause. Naturally, he was a little confused. It was just one of those plays that was a freak accident. But hopefully both men will be OK.”

According to NHL.comKozari worked 1,151 regular season games and 136 postseason contests.

Penguins coach Mike Sullivan said: For every athleteHe caught only a small glimpse of what he called a “scary moment.”

“I caught it out of the corner of my eye,” Sullivan said. “At the last second, they collided and I think it was a helmet-to-helmet collision. It was a really scary collision because I don't really think Steve would have been able to break his fall.

“That was a scary moment.”
