After the Brewster fight he had a ton of injuries that kept him from training properly, I remember the weigh in for the Briggs fight, He looked lethargic and had alot of fat compared to his previous fights. I seen a picture of him recently, looks like he is in good shape again and has put on a decent amount of muscle. We'll have to see if being out of the game put to much rust on him though.
Take a look, this is a new picture of liakhovich taken couple of weeks ago. http://www.fightnewsextra.com/cc/2009stories/09-whitewolf.htm
