PHILADELPHIA (973espn.com) - The Eagles offense suffered another major blow on Monday when running back Jay Ajayi was placed on injured reserve after tearing his ACL during a 23-21 loss to the Minnesota Vikings on Sunday.

It's just the latest blow to a disjointed offense which has two receivers on IR -- Mike Wallace (fractured leg) and Mack Hollins (groin) -- and two other running backs dealing with nagging injuries -- Darren Sproles (hamstring) and Corey Clement (quad). Meanwhile, quarterback Carson Wentz missed the first two games while rehabbing from ACL/LCL surgery and receiver Alshon Jeffery was out for three games due to shoulder surgery.

Ajayi, who is in his walk year from a contract standpoint, had been playing through a transverse process fracture in his back suffered against Tampa Bay in Week 2.

All the musical chairs have resulted in an offense which has been under 24 points in all five games during a 2-3 start, a sharp downturn for a team that was over that number a league-high 12 times during the 2017 campaign en route to a Super Bowl LII championship.

With Ajayi gone for the season, the Eagles need Sproles and Clement back in action sooner rather than later and the latter was active against the Vikings but did not play. Wendell Smallwood and rookie Josh Adams are also available for Doug Pederson.

Ajayi's spot on the 53-man roster was taken by defensive tackle T.Y. McGill, who was picked up on waivers from the Los Angeles Chargers.

Philadelphia was without nose tackle Haloti Ngata against the Vikings and the DT position has been an issue outside of Fletcher Cox.
