PHILADELPHIA - The Eagles placed lead running back Jay Ajayi on injured reserve Monday, a major blow to an offense that has struggled to score points over the first five games of the season.
Ajayi tore his ACL Sunday against the Minnesota Vikings, a source told ESPN's Adam Schefter.
Philadelphia has been hit hard by injuries at the offensive skill positions.
Receivers Mike Wallace (fractured leg) and Mack Hollins (groin) were placed on injured reserve earlier in the season, and running backs Darren Sproles (hamstring) and Corey Clement (quad) have been unable to stay on the field.
