The Sharks have dealt with their fair share of knee issues over the last few seasons, and they're going to have to work through another one over the next few weeks.

Defenseman Radim Simek will miss about two weeks as he needs to undergo a procedure on his surgically repaired right knee, Sharks general manager Doug Wilson told reporters in Tampa on Sunday before San Jose's game against the Lightning. 

Simek tore his ACL and MCL in March, and had surgery soon after. He initially was projected to rejoin the team at the start of the season, but Simek didn't return to game action until Nov. 5. In 16 games this season, Simek has scored four points (one goal, three assists) and posted a minus-12.

Despite those pedestrian numbers, Simek's presence in the Sharks lineup makes a big difference. San Jose is 4-10-1 when Simek has not played this season and 11-4-1 with him in the lineup.

Sharks coach Peter DeBoer said Tim Heed would play in Simek's place Sunday. Although Heed has played well in his last couple of games, it's still possible Brent Burns and Erik Karlsson will play more and share Simek's responsibilities, much like they did at the start of the season when Simek initially was out.
