Tampa Bay will have to continue their push for an Eastern Conference playoff spot without No. 1 goaltender Mathieu Garon.
The Lightning said Wednesday that Garon will be out three to four weeks with a torn groin muscle.
The 34-year-old netminder left Tuesday's home game against Ottawa after just four minutes. The Lightning would go on to lose 7-3 to the Senators.
Garon had taken over the No. 1 job from veteran Dwayne Roloson earlier this season. He was 23-16-4 in 48 appearances, with a 2.85 goals-against average and .901 save percentage,
Tampa Bay, tied for 10th in the East, next play Thursday on the road against Washington.
The Lightning have called up former Memorial Cup winning goaltender Dustin Tokarski from the American Hockey League.
Tokarski, 22, has yet to play a regular season NHL game.
