Jackson left the field and headed to the locker room after a catch that set the Eagles up in Giants territory and led to an Alex Henery field goal. But while NBC's Michele Tafoya reported that Jackson was taken to the locker room for further examination of his right knee, and that his return was questionable, he returned after missing a series, with Al Michaels telling the NBC audience that Jackson had been evaluated for a concussion.
Evidently, Jackson was cleared in that evaluation. His first play back — a 50-yard catch to get the Eagles to midfield from their own 2 that was immediately nullified by a Jackson penalty for taunting — didn't exactly serve as evidence for Jackson's health. It was the sort of thing that DeSean Jackson would do, concussion or no.
