The Philadelphia Eagles placed starting running back Jay Ajayi on injured reserve Monday due to a torn ACL, according to ESPN's Adam Schefter.
Ajayi previously landed on the injury report before the Eagles' Week 1 clash with the Atlanta Falcons because of a foot injury, but he was cleared in time for the season opener and found the end zone twice in a narrow 18-12 win.
The 25-year-old then suffered a back injury in Week 2 against the Tampa Bay Buccaneers that forced him to miss the Eagles' 20-16 Week 3 win over the Indianapolis Colts.
