Tommy Wingels left Thursday night's Sharks-Panthers game in the first period after going hard into the boards, and did not return with a possible left shoulder injury.
After the game, a 2-1 Sharks shootout win, coach Pete DeBoer said that only that Wingels is "probably out for a little while" and that he would know more on Friday.
Wingels got tangled up with defenseman Aaron Ekblad, lost his footing, and went careening into the wall before going off under his own power. The 27-year-old forward has played in all 56 games this season, with 15 points (6g, 9a) and 45 penalty minutes. Wingels led the Sharks with 156 hits entering Thursday night.
Two candidates for recall if Wingels is to miss an extended period of time are forwards Ben Smith and Barclay Goodrow, currently both in the AHL with the Barracuda. Since being waived and reassigned on Jan. 22, Smith has seven goals and nine points in 11 games. Goodrow, who was reassigned on Dec. 20, has a team-leading 15 goals (and 27 points) in 38 minor league games.
Mike Brown also remains with the team, and has been scratched for the past nine games.
Thursday marked the second time Wingels had to leave a game early. On Jan. 11 in Calgary, he collided head-to-head with Joonas Donskoi in the first period but returned to play the next night in Winnipeg.
The Sharks continue a five-game road trip in Carolina on Friday.
