The Jacksonville Jaguars needed their defense to be at 100 percent if they wanted to beat the Kansas City Chiefs in Week 1. Unfortunately for the Jaguars, linebacker Myles Jack had other plans.
Jack failed to make it to halftime during the contest after he was ejected for throwing punches.
Jack initially got into it with Chiefs receiver Sammy Watkins. Demarcus Robinson came to Watkins’ defense, and Jack responded by punching Robinson in the helmet. Jack threw the punch in front of a ref, who immediately threw a flag.
After being ejected, Jack tried to go after the Chiefs’ sideline.

Jack, who has emerged as one of the Jaguars’ key defensive players over the past three seasons, signed a four-year, $57 million extension with the team in August.
The Chiefs eventually won the contest, 40-26.
