Cleveland Browns rookie quarterback Colt McCoy still isn't ready to practice because of an ankle injury that likely will keep him out for a third consecutive game.
McCoy hasn't played since sustaining a high left ankle sprain Nov. 21 at Jacksonville, his fifth start.
"We have a shot for him practicing this week," Browns coach Eric Mangini said Wednesday. "I wouldn't say it's a slam dunk, but I think it's a possibility."
Mangini said McCoy was able to work with trainers Tuesday.
"It's different when you're thinking about reading coverages, letting your body react," the coach said. "That's sort of the next step, and it remains to be seen."
Jake Delhomme started the past two games for the Browns (5-7), who will travel to Buffalo (2-10) on Sunday. McCoy said last week that he wants to play again this season.
