KNOXVILLE (WVLT) -- The Cotton-Eyed Joe dance club turned into a fight club Saturday night, playing host to a nine-fight boxing card that included Knoxville native Alonzo "Big Zo" Butler, who was tuning up for a fight that will be broadcast on ESPN this January.

And Butler didn't disappoint. The heavyweight knocked out his opponent in the second round, earning the 28th victory of his career and serving as a successful tuneup for his upcoming nationally televised bout.

"I just wanted to tune up a little more before I go on ESPN, just tweak everything, get my mind right and my weight down," Butler said after the fight.

"I was rusty, but other than that everything was great."
