Watch out, NFL ... it looks like Cleveland Browns star Gary Barnidge is ready to open a can of whoop ass this season ... and his first victim is a PRO WRESTLER!!
The Pro Bowl TE teamed up with his buddy, DeAngelo Williams, to take down Impact Wrestling star Davey Richards Thursday night ... and Barnidge destroys him with a devastating body slam.
The vid is great ... Barnidge and Williams really get into it and celebrate the victory by joining the fans in Moose's trademark chant.
Remember: Don't try this at home, kids ... leave it to the pros.
