We can't discredit Sam Alvey for trying, but "Smile'n" certainly did not leave Ultimate Fighting Championship (UFC) brass very happy following his "Perfect Tan" sponsor on his chest (pic here) during his UFC Fight Night 65 battle against Dan Kelly last night (Sat., May 9, 2015) in Adelaide, Australia.
Apparently, the potential loophole is against UFC policy, as Tom Wright -- a UFC executive -- noted at the post-fight press conference (replay here).
His words:
"Fighters definitely can't do that. It's against our policy. You can put your sponsors on your shorts.
