CHICAGO (AP) — Tampa Bay coach Jon Cooper says he isn't sure who will start in goal for the Lightning in Game 3 of the Stanley Cup Final.

Ben Bishop left midway through the third period of Tampa Bay's 4-3 victory over Chicago on Saturday night. He returned for a brief stretch and then left for good. Andrei Vasilevskiy made five saves to help close out the win.

There was no word from the Lightning on Sunday on why Bishop departed. Cooper indicated he could be available for Monday night's game, and he might know more at the morning skate.

Cooper says it would be a blow for Tampa Bay if Bishop is unable to play, but the team is confident it can win with Vasilevskiy in net.
