Arizona Cardinals head coach Jonathan Gannon is being investigated by the NFLPA after he appeared to strike running back Emari Demercado following his costly fumble in Sunday’s loss to the Tennessee Titans, according to a report.

The NFL Players Association (NFLPA) told USA Today that it is “investigating” the heated sideline interaction in the fourth quarter that came after Demercado dropped the ball before reaching the goal line in what would’ve been a 76-yard touchdown.
