Tampa Bay Lightning forward Alex Killorn is "doubtful" for Game 5 against the Montreal Canadiens on Wednesday, head coach Jon Cooper announced.

Killorn was not among the players on the ice for Wednesday's morning skate.

Killorn has been hampered by a lower-body injury he suffered in Game 1, blocking a shot from the Canadiens' Jeff Petry with his left ankle. Killorn played just one shift following the injury. 

The 31-year-old, who has spent all nine of his seasons in the NHL with the Lightning, has recorded eight goals and nine assists this postseason.
