Broncos' Peyton Manning questionable Monday vs. Bengals

Still dealing with a lingering thigh injury, Denver Broncos quarterback Peyton Manning has been ruled as questionable for Sunday's game against the Cincinnati Bengals.

The designation leaves his status up in the air, but Manning will almost certainly be in the lineup after participating in practice throughout the week.

The 17-year veteran has put together another incredible year, throwing for 4,143 yards and 37 touchdowns against only 11 interceptions.
