“You have to listen to your body,” Crosby said.

He said that passing a baseline concussion test was “encouraging, but it’s not everything.”

He added: “I skated the following day after with exertion. I just didn’t feel right. After talking with everyone I figured it was better to be cautious and not take any chances. That’s where I’m at right now.”

But now the comeback of the best player in hockey has been derailed.

“It’s the same recovery routine again, but hopefully not as long,” Crosby said.
