However, Chargers fullback Lorenzo Neal, who is recovering from a broken leg, is inactive for the game.
"It's pretty sore," Gates told the San Diego Tribune on Friday. "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.
Brandon Manumaleuna was slated to take Gates' starting spot if he wasn't able to play.
"Right now, keeping pressure off of it is the best thing for it," Gates said. "It's just imperative that I keep the swelling out and I keep pressure off of it."
Even with Antonio Gates playing, I don't think he'll be as big a factor this game as everyone is making him out to be, especially if he plays hurt. The Colts should roll in this one.
However, the interesting thing to note is that yesterday both the home-team favorites won. Will that happen again today? My guess is yea, but there is more speculation about the Giants upsetting the Cowboys than the Chargers upsetting the Colts.
