A lot of players have been nicked up during training camp.

Harrison maybe the latest to have to undergo a knee scope.

Pittsburgh Steelers linebacker James Harrison might need to have surgery if the swelling continues in his injured left knee, his agent told the Beaver County Times.

If swelling continues, Harrison will be shut down to undergo the procedure.

Parise thinks Harrison could return a week after the surgery, but it could be tough for the 34-year-old Harrison to be ready to play after not participating in training camp.

*Update*

He had the surgery.

#Steelers LB James Harrison had scope on his left knee this morning and it “went well,” according to one source.
