SAN JOSE – Sharks center Tomas Hertl is out indefinitely with a right knee sprain, general manager Doug Wilson said in a statement released by the team on Monday.
"Hertl will undergo a minor procedure tomorrow under the direction of the Kaiser Permanente medical team. Following the procedure, Hertl will proceed with his rehabilitation schedule in San Jose.
"No timetable has been set for his return to game action."
Hertl suffered the injury on Nov. 17 in St. Louis on what looked like a relatively innocent collision with the Blues’ Jori Lehtera in the second period.

In 17 games this season, Hertl has nine points (4g, 5a).
This is the third time Hertl has injured his right knee. On Dec. 19, 2013, he collided with the Kings’ Dustin Brown, requiring surgery to repair his MCL and PCL ligaments. He missed approximately four months, returning late in the regular season.
In Game 2 of the Stanley Cup Final on June 1, 2016, Hertl injured the knee again when Pittsburgh’s Patric Hornqvist hit him late in the game. He missed the remainder of the series, a six-game defeat for San Jose, as well as the World Cup in September where he was due to compete for the Czech Republic.
To fill his spot on the roster, the Sharks recalled center Danny O’Regan from the Barracuda on Monday. The 22-year-old was set to make his NHL debut on Monday night against the Devils.
