Goalie Anthony Stolarz has another knee surgery, leaving Flyers with less depth in minors

Flyers goaltender Anthony Stolarz underwent another knee surgery and will be sidelined indefinitely, general manager Ron Hextall announced Friday.

Stolarz, 23, had surgery on his left knee Thursday to repair a meniscus tear, according to Hextall.

In April, Stolarz had surgery on his right knee to fix a torn medial collateral ligament.

Subsequently, the Flyers surprisingly protected the Jackson, N.J., native in the June expansion draft.

The AHL's Lehigh Valley Phantoms signed veteran goalie Leland Irving recently, and on Friday they signed another veteran, Mark Dekanich.

Irving, 29, was a first-round selection by Calgary in 2006.

Dekanich, 31, went 21-12-1 with a 3.04 goals-against average and .910 save percentage last season with Reading in the ECHL. (He played one game with the Phantoms.) In 2006, he was drafted by Nashville in the fifth round.

Stolarz, a second-round selection in the 2012 draft, was expected to divide duties with Alex Lyon this season in Lehigh Valley.

In seven appearances with the Flyers last season, Stolarz had a 2.07 goals-against average and .928 save percentage. He had a 2.92 GAA and .911 save percentage in 29 games with the Phantoms last season.

A few weeks ago, while working out at the Flyers' training facility in Voorhees, Stolarz said: "I'm taking baby steps to get healthy and just make sure I'll be able to start the season on time. I'm probably 90 percent right now."

That was before he injured his healthy knee.
