Greg Hardy had a rough night on Friday.

The former NFL defensive end turned boxer was brutally knocked out in the 17th round of the Team Combat League.

Alexander Flores landed the blow at Hardy’s expense.

The end of Hardy’s football career was shrouded in controversy. He was charged with domestic violence and arrested for cocaine possession. He last played football during the 2015 season for the Dallas Cowboys.
