Rodgers may be far from 100 percent

— -- Green Bay Packers quarterback Aaron Rodgers' calf muscle has a slight tear in it in addition to being significantly strained, according to league sources.

The injury is not expected to prevent Rodgers from playing in Sunday's divisional round playoff game against the Dallas Cowboys, but it could affect how mobile and effective he is.

"There's no question he will play, but there's also no question he will not be 100 percent," said one doctor familiar with the injury. "The question is whether he'll be 95 percent or 50 percent."

The Packers are aggressively treating the injury with the hope he can be as well as possible. Each person responds differently to calf injuries.

Rodgers was limited to the team practice periods on Thursday. Coach Mike McCarthy said that his quarterback's mobility "looked good." The Packers' next scheduled practice is Saturday.

Green Bay held Rodgers out of practice on Wednesday, and how active he will be the rest of the week still is unknown.

What's certain is that Rodgers' calf is not right heading into Sunday's game, and now he will try to overcome it, just as he did in the regular-season finale to help his team beat Detroit.
