When Lightning RW B.J. Crombeen went off the ice after his first-period fight with Zac Rinaldo, he was put through an NHL-mandated protocol that looks for concussion symptoms.

Crombeen was brought to a quiet area and put through "a battery of tests," head athletic trainer Tommy Mulligan said, that included simple questions about where he was and what just happened to him, and more complicated tasks such as remembering word sequences.

He also was put through physical tests — on the stationary bike, pushups, situps — to see his reaction to an increased heart rate. Despite Mulligan saying Crombeen "did well with that" and showed no symptoms, the decision was made to keep him out of the game.

"He wanted to go back but I decided not to put him back," coach Guy Boucher said.

Added Mulligan: "We wanted to make sure he didn't have any lingering issues. Sometimes symptoms don't set in until after the fact."

Crombeen said he feels fine.

"I was a bit wobbly when I went to get up," Crombeen said. "It was probably better to play it safe than sorry to make sure no symptoms come up and I'm ready to go for the next game."
