In the podcast he claims a boxing bout one week before his tapout fight against Matt "sunshine" Fiordirosa, which took place on 5/19/2007 at Reality Fighting.
So, according to these stats, he did not have a boxing bout one week before his tapout fight...unless there is another boxing record I can't find.
Also interesting is that he was under suspension for a busted eardrum by the West Va. Athletic commission from 12/30/07 - 2/13/08, yet he fought an MMA bout against Leon Tyree, which he won via Submission (Triangle Choke) at the "No Escape the Cage" show 2/9/2008...before his West Va suspension was complete. This is simply nitpicking on my part since his suspecion was only days away, but it was an interesting tidbit I found while looking up his boxing record.
