John Harbaugh pulled out his red challenge flag rather early in the Baltimore Ravens' Thursday Night Football matchup against the Cincinnati Bengals at M&T Bank Stadium in Week 10.
On the Bengals' first offensive possession, quarterback Joe Burrow steered the offense deep into the red zone and set up a first-and-goal from the 5-yard line. He connected with tight end Mike Gesicki for a three-yard reception near the sidelines, but Harbaugh wasn't convinced the veteran completed the catch.
