The Miami Dolphins ruled quarterback Jay Cutler out for Thursday night's contest against the Baltimore Ravens, as he deals with multiple cracked ribs.

Cutler suffered the injury in a Week 7 game against the New York Jets and four days appears too short a time for the veteran to heal for the Week 8 matchup.

He was replaced in last week's contest by Matt Moore, who will presumably draw the start for the 4-2 Dolphins.

Miami signed David Fales to serve as Moore's backup while Cutler is out.
