Cardinals fine head coach Jonathan Gannon $100K for altercation with player after big blunder: reports

The Seattle Seahawks beat the Arizona Cardinals 23-20, and Kyler Murray struggled during the loss. Colin Cowherd asks if it’s time for the Cardinals to move on.

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.
