Jon Moxley's job Wednesday night was to entertain the masses with a gruesome wrestling match ... and it's safe to say, he nailed the assignment.
The AEW superstar clashed with his nemesis, Adam Copeland, in a Street Fight during "Dynamite" in Omaha, Neb. ... and he put on quite the painful show.
Per the rules of the match, the two were allowed to use weapons ... so, at one point, Copeland brought out a spiked board and tossed Moxley directly onto it.
