Philadelphia Eagles have placed starting running back Jay Ajayi on injured reserve, with the NFL Network reporting he is out for the season with a torn anterior-cruciate ligament.
The Eagles announced they were shelving the English-born running back on Monday, with defensive tackle TY McGill coming in to replace him.
Ajayi was reportedly injured during Sunday's 23-21 defeat to the Minnesota Vikings.
The 25-year-old accumulated 29 yards on eight carries in the loss to the Vikings and after the game publicly questioned the lack of running plays called by the coaching staff.
"Obviously we want to be able to run the ball early and start that rhythm early, in the beginning of the game," Ajayi told ESPN.
"If I remember correctly, we had maybe three carries at the end of the first quarter.
"With the offensive line that we have on this team, running the ball like that, that doesn't make sense to me."
