Steelers QB Ben Roethlisberger on track to start against Broncos

Pittsburgh Steelers quarterback Ben Roethlisberger is expected to start Sunday against the Denver Broncos after responding well to Friday's practice, a source told ESPN's Sal Paolantonio.

Roethlisberger, who suffered a sprained AC joint and ligament damage in his right shoulder after a hit from Vontaze Burfict during the Steelers' wild-card win over the Bengals, was a full participant during Friday's practice.

Roethlisberger, listed as questionable, will make the trip to Denver with the team and will be evaluated by medical staff on Sunday morning, the source told Paolantonio.

Steelers coach Mike Tomlin says Roethlisberger did everything he was asked on Friday.

While the team remains optimistic Roethlisberger will play, wide receiver Antonio Brown and running back DeAngelo Williams are officially out. Brown is still going through the NFL's concussion protocol after getting hurt in the final moments against the Bengals. Williams will miss a second straight week with an injured right foot.
