General manager Ron Hextall provided the update Wednesday, saying Couturier was injured Aug. 10 in an exhibition game.
Hextall expects Couturier to be a limited participant in training camp when the Flyers get on the ice Sept. 14 and for him to be full-go halfway in. Hextall says it's not the same injury the 25-year-old suffered when he damaged the medial collateral ligament in his right knee during the playoffs when he collided with teammate Radko Gudas in practice.
Couturier is coming off a breakout season in which he was promoted to Philadelphia's No. 1 center and set career highs with 31 goals, 45 assists and 76 points. He finished third on the team in scoring.
