Chael Sonnen is bringing some serious heat to the table with the sixth edition of Submission Underground on Dec. 3 in Portland, OR!

Battle of SUG Champions

Submission Underground 6 features some of the winningest veterans in SUG history. In the main event, world champion, current UFC fighter, and previous SUG champion (whew) Gilbert Burns faces off against SUG champion and one of the best MMA grapplers of all time in Jake Shields.
