Byfuglien was noticeably wobbly and struggled to his feet after colliding with Penguins defenceman Jamie Oleksiak in the second period of Tuesday's game and needed help from teammates to get back onto the team's bench.

Byfuglien was then pulled from the game to go through the NHL's concussion protocol. He passed testing and returned to the game later in the frame, logging a total of 22:03 of ice time in the loss.

Dreger said there is no assumption from the league, adding the "NHL regularly follows up on a nightly basis to assure protocol is being appropriately enforced."

Jets head coach Paul Maurice said after the contest that Byfuglien was "fine."

“There isn’t really a whole lot there. He went in, got checked out. He’s fine,” Maurice said. “Came back out and played.”
