Shepard won't return to Monday's game at Kansas City due to a quadriceps injury, per Lisa Salters of ESPN.
On the Giants' final drive of the first half, Shepard went down with a non-contract injury and stayed on the turf for a bit before making his way to the sideline, according to Pat Leonard of the New York Daily News. Shepard was favoring his left leg and attempted to stretch it out, but the team won't take any chances with the wide receiver after halftime. He's no stranger to lower-body injuries this season, having dealt with issues with both of his hamstrings and missing three games as a result. With just one contest before a Week 10 bye, New York could exercise additional caution with Shepard and hold him out Sunday against the Raiders to ensure he's good for the second half of the campaign. Ultimately, though, his activity level in practice this week will determine his availability.
