In what could possibly be one of the biggest upsets of the year thus far, unknown Light-heavyweight Emanual Newton faced off against former Strikeforce 205lb Champion King Mo Lawal in the semi-final of a Light-heavyweight tournament at Bellator 90.

Newton shocked the entire arena at 2:35 of the first round. Newtown and Lawal had a brief exchange in which Newtwon turned his back causing Lawal to drop his hands with a false sense of temporary safety, only to be cracked instantly by a vicious, fast, well-timed and obviously unexpected spinning backfist.
