From the Pittsburgh Tribune-Review's Rob Rossi:
Evgeni Malkin is experiencing concussion symptoms, including severe headache and mild disorientation, multiple sources confirmed Saturday.
Malkin was injured early in the third period of the Penguins’ win over Florida at Consol Energy Center on Friday.
He did not finish the game after sliding into the end-zone boards. The back of his head appeared to bounce off the boards, and Malkin’s neck snapped back in a seeming whiplash motion. Malkin was slated for further medical evaluation Saturday, coach Dan Bylsma said after the game Friday night.
Malkin was not available for comment.
He is not expected to play against Tampa Bay at home on Sunday night, the sources said.
