Pittsburgh Steelers star wide receiver Antonio Brown is not expected to be ready for the wild-card round of the playoffs, a league source told ESPN.

If Pittsburgh wants to enhance its chances of having Brown for the start of its playoff run, the Steelers would have to clinch a bye for the wild-card round.

The Steelers are vying for one of the AFC's two top seeds, which would carry a bye and an extra week of rest for Brown and the rest of the players.

Brown suffered a partially torn calf muscle in Week 15 against the New England Patriots. The Steelers already have ruled him out for their game Monday against the Houston Texans.
