The Kelce Bros. weren't the only superstar athletes at the Cavs game Tuesday night -- the world's best eater, Joey Chestnut, rolled through Cleveland as well ... putting his unbelievable abilities on display for everyone in attendance!!
Jaws returned to Rocket Mortgage FieldHouse for the Wine and Gold's home matchup against the Boston Celtics ... but the real contest went down at halftime, when the hot dog champ faced off against three normies in a pierogi challenge.
Chestnut -- who's by far the most famous figure in professional eating -- completely wrecked the field .
