Injuries: Philadelphia Eagles place OL Andrew Gardner on injured reserve

Already thin on the offensive line, the Philadelphia Eagles announced Tuesday starting guard Andrew Gardner has been placed on the season-ending injured reserve  list.

He suffered a foot injury in Sunday's game against the New York Jets.

Gardner, who signed a three-year contract extension in the offseason, started the first three games for the Eagles - who cut guards Todd Herremans and Evan Mathis in the offseason.

The Eagles signed offensive line Julian VanDervelde to replace Gardner on the roster.
