Eagles defensive end Joe Ostman, who injured his left knee in Sunday’s practice session at Lincoln Financial Field, was placed on injured reserve Tuesday.

Ostman, who was in the locker room using crutches on Tuesday, said he has a torn ACL.

After spending last season on the Eagles’ practice squad, Ostman had been having an excellent training camp and was in the hunt for the fourth spot in the Eagles’ defensive-end rotation, with Brandon Graham, Vinny Curry, and Derek Barnett.

“I felt like camp was going pretty well, I felt confident out there,” Ostman said. “I still had a lot of stuff to work on, but I felt like I was making some progress and felt good about it. But it’s just part of the game.”

In a corresponding move Tuesday, the Eagles signed veteran defensive end Kasim Edebali. Edebali, a Boston College product who will turn 30 this month, has played in 62 games since being signed as an undrafted free agent by the New Orleans Saints in 2014.

The 6-foot-2, 250-pound Edebali has eight career sacks. Five of them were with the Saints in 2015.

Eagles safety Malcolm Jenkins said that Ostman was one of the standouts of training camp before getting injured, and praised the defensive end for his energy level on the field.

“It’s really tough because he’s a guy who works super hard,” Jenkins said. “We always track how far guys run and how fast they run and he — literally every single day — leads the defensive line in yards run every practice.”

Ostman said he’s not sure when he’ll have surgery, but that it will happen “shortly.”
