Steelers' Keeanu Benton: Downgrades to limited Friday

Benton (ankle) was a limited participant in Friday's practice, Teresa Varley of the Steelers' official site reports.

Benton logged a full practice Thursday, so a drop in participation Friday means the nose tackle likely suffered a setback with his ankle injury. The 24-year-old will have one more opportunity to return to full participation in hopes of avoiding an injury designation for Monday night's game against the Dolphins.
