By Greg Jennings' math, he has only had two concussions in his life. By the Green Bay Packers' medical staff's, he has had three. Whatever the case, the Packers two-time Pro Bowl wide receiver was just happy to be back on the practice field Sunday after sitting out more than two weeks following a concussion apparently sustained Aug. 3 during the Family Night Scrimmage. Jennings revealed Sunday that he actually was suffering from headaches after a hit in practice two days before the scrimmage, and that might have been the reason it took him so long to get back on the field.
