Brent Celek suffered a concussion on the very first play of the game against the Bucs Sunday. He is the third member of the offense to be sidelined by a head injury in recent weeks, joining Michael Vick and LeSean McCoy.
Celek was tackled by a pair of Tampa defenders after a modest gain and had trouble getting to his feet. He eventually walked off and was evaluated by trainers on the sidelines before heading inside.
Celek was replaced by Clay Harbor.
The offense has been ripped apart by injuries. Four-fifths of the offensive line is gone. Same with the starting quarterback, the starting running back and No. 1 wide receiver DeSean Jackson, who is on injured reserve with fractured ribs. And now, their tight end.
Nnamdi Asomugha left early in the second quarter with a neck and thigh injury. The veteran corner jumped up to make a play on the ball and was upended by Dallas Clark. Asomugha landed flat on his upper back and stayed down for some time before walking gingerly off the field.
