Antonio Gates' limp suggested that he's going to have a hard time playing Sunday when his San Diego Chargers face the Indianapolis Colts in a divisional-round playoff game. But with two days left to treat his dislocated left big toe, the star tight end said the decision whether he plays will be made Sunday morning. "It's definitely going to be a game-time decision," Gates said Thursday after missing his second straight day of practice. "I'm not going to make any decisions before that. We're just going to wait to see how it feels on Sunday." Gates was hurt in the second quarter of Sunday's 17-6 wild-card win over the Tennessee Titans and didn't return.
