Toronto Maple Leafs winger Joffrey Lupul left the game Monday night against the Columbus Blue Jackets at Air Canada Centre in the second period.
Lupul sustained a groin injury and did not return to the ice for the third.
"Sore groin, so I don't know what that means," Maple Leafs coach Randy Carlyle said. "He just said he pulled his groin."
Lupul, 30, missed two games last month with a bruised foot. He has eight goals and seven assists in 22 games this season.
Toronto lost to Columbus, 6-0.
