Chris is pursuing other interests at this time. After this past year, and the Gammo-O debacle...he decided to secure a better future for himself and his family that isn't dependant on BB related work.
He's only 30, so I wouldn't rule out him coming back at some point in the future, but it's safe to say it woudn't be for at least a few years if at all...
Right now, he's keeping in training and thinking about doing some UFC style fighting, as he has a pretty decent background in wrestling/ boxing/ fighting...
If Chris' focus and energy is anything like it was in getting his pro card...I wouldn't doubt he does very well in MMA.
