Stamkos left the game in the first period after he fell awkwardly against the boards while killing a penalty. He was unable to put pressure on his right leg as he skated to the bench. He played four shifts and had in 2:07 of ice time.
Stamkos signed an eight-year, $68 million contract with the Lightning on June 29 and is off to a fast start this season. He scored his ninth goal at 6:09 of the first period to give Tampa Bay a 2-0 lead. His 20 points are tied for second in the NHL with Dallas Stars forward Tyler Seguin, one behind Winnipeg Jets forward Mark Scheifele and Lightning forward Nikita Kucherov.
Injuries have slowed Stamkos' NHL career. He broke his right tibia after crashing into the goal post during a game at the Boston Bruins on Nov. 11, 2013, and missed 45 games. He also missed all but one game of the Lightning's run to the 2016 Eastern Conference Final while recovering from a blood clot near his collarbone.
The Lightning continue a four-game road trip against the Buffalo Sabres at KeyBank Center on Thursday (7 p.m. ET; MSG-B, SUN, NHL.TV).
