San Diego Chargers' tight end Antonio Gates acknowledged he is in a race against time to get fit for Sunday's AFC divisional playoff game against Indianapolis, a newspaper report said. "Right now, it's still a game-time decision," the player told the San Diego Tribune on Friday. "It's pretty sore. It felt good Tuesday, but it doesn't feel as good today [Friday]. It's a tricky situation, it really it is." Gates dislocated his left big toe late in the second quarter of Sunday's 17-6 wild-card win against Tennessee and didn't return. He has been undergoing intensive therapy on the injury in the hope of being available to help San Diego in its difficult away game in Indianapolis but conceded he may require surgery. "Unfortunately, I really can't say at this point whether or not I'm going to have surgery because it's still a 50-50 chance," Gates told the paper.
