Russell from Big Brother

So I was hanging out with some friends yesterday, and the subject of Russell from Big Brother came up. They're always talking about how he's an MMA fighter, but none of us had ever heard of him. So I did a bit of research, and this is what I found. Russell Kairouz trains with Team Alpha Male, who's most famous fighter is definitely Urijah Faber. As far as I can tell, Russell only has one fight on his record, which is a loss. He fought David Marshall, who beat him 1:24 in the first round with a triangle choke. But the thing is, this fight was in 2004. I can't find any mention of fights after that date. It kind of seems like the Big Brother producers are talking up his MMA history so that they can put him in the hot headed, alpha male role, but I could be wrong. If anyone knows of additonal fights, please let me know!
