Teddy Bridgewater was cleared to leave hospital on Monday after suffering a head injury during the Denver Broncos' 15-10 defeat to the Cincinnati Bengals.

The Broncos quarterback was carted off the field after landing on his head and shoulder while he diced for a first down in the third quarter of the game at Empower Field at Mile High on Sunday.

Bridgewater was kept in hospital overnight as a precaution, but the 29-year-old has now been discharged.

Denver (7-7) confirmed Bridgewater has entered the NFL's concussion protocol.

Drew Lock replaced Bridgewater and the stand-in signal-caller passed for 88 yards following his introduction, completing only six of his 12 throws.

The Broncos sit third in the AFC West behind the Kansas City Chiefs (10-4) and the Los Angeles Chargers (8-6) with three weeks of the regular season remaining.

They face a trip to take on the Las Vegas Raiders for a Week 16 showdown on Boxing Day.
