The message was mixed on rookie safety Earl Wolff. Coach Chip Kelly said Wolff won't play Saturday night if he doesn't practice. Wolff, battling an aggravated knee injury, didn't practice Tuesday or yesterday. But Wolff said he still thinks he can play, and expects to take part in today's practice, even though, as he noted, that is little more than a walkthrough and won't give the knee much of a test. If Wolff can't play, the Eagles might go back to rotating Patrick Chung and Kurt Coleman, as they were doing before Coleman's hamstring injury . . . Special-teams cog Colt Anderson did practice yesterday and said he feels ready to return from the knee injury that has kept him out of the last two games . . . Center Julian Vandervelde (back) did not practice . . . LeSean McCoy seemed to be looking to set a tone for younger teammates in his news conference yesterday. "We're made for the playoffs. Everybody's so excited to be here, but we should be here," McCoy said . . . Remember, if you purchased playoff tickets online, you have to print them out and bring them to the game, you can't just show the confirmation email at the gate.
