Arkansas Coach Eric Musselman Parties Shirtless After Upset Win Over #1 Auburn

Eric Musselman is a man of his word — the Razorbacks head coach partied shirtless after a HUGE upset win over #1-ranked Auburn on Tuesday night … and it was epic!!

Here’s the deal — Muss met with a group of Arkansas students outside Bud Walton Arena in Fayetteville before the game … and was asked if he would do a topless celebration if they knocked off the top team in the country.

Not only did coach make the promise, he kept it after Arkansas knocked off Auburn, 80-76 … ripping his shirt off and celebrating like crazy!!

Check out the video, Muss was the center of attention, dancing, and having fun … all while wearing a shoulder brace.

In case you were wondering, Eric is wearing that sling due to shoulder surgery he had to repair a torn rotator cuff in January.

But, somehow, the guy managed to back up his end of the deal despite the injury … and thanked local officials for allowing him to rage peacefully with the crowd.

“Can’t thank these two enough for letting me celebrate with our fans tonight! Detective Ramirez & Sargent Robertson appreciate you both! #HogYeah,” Muss wrote on Twitter.
