The Ravens’ rugged defense could be without one of its top playmakers Sunday. And it’s not LB Terrell Suggs.

CB Samari Rolle, who made an interception during last week’s divisional-round victory over the Titans, hasn’t practiced all week because of a thigh injury and was listed Friday as doubtful for the AFC Championship Game against the Steelers.

The Ravens held out four key starters — WRs Mark Clayton and Derrick Mason, CB Samari Rolle and LB Terrell Suggs — from practice for the second straight day on Thursday.
