The Arizona Cardinals have reportedly fined head coach Jonathan Gannon $100,000 for his sideline altercation with running back Emari Demercado.

Gannon was upset after Demercado dropped the football before crossing the goal line on what should have been a 72-yard touchdown that would have put Arizona up 28-6 early in the fourth quarter.

Instead, the Cardinals went on to lose to the Tennessee Titans , 22-21.

A video posted to social media showed Gannon approaching Demercado, who was being consoled by left tackle Paris Johnson after the mistake, and confronting him. Gannon appeared to get in Demercado’s face before making brief contact with the running back's arm as he walked away.
