what happened to Matt Korobov?

It seems Korobov had some visa problems but is coming back Oct 2012. Read an article that said he'd like to get a fight with Jonathan Gonzalez, that would be an interesting match up.

Korobov was making solid progress-he was fighting fairly regularly and was beating respectable journeymen like Walker and Findley by his 14th fight. Than his competition took a step back and he's been off for a while, his career has stalled.

He's only 29 so there's still plenty of time to get back on track. He looked like a promising prospect, it would be nice to see him reach some of his potential.
