UFC Light Heavyweight champ Jon Jones has released a new video showing him and his brother Art Jones, of the NFL Baltimore Ravens, "training" for his April 21 UFC 145 title fight with Rashad Evans. The training involves some Nerf guns and Nerf bullets. Hopefully no one was seriously hurt.

SBN coverage of UFC 145: Jones vs. Evans

Jones, a former teammate of Evans' at Greg Jackson's Martial Arts in Albuquerque, New Mexico, has a bitter rivalry with Evans that resulted in the latter leaving Jackson's after several years training there. Greg Jackson has announced he'll be cornering Jones against Evans, despite earlier protestations that he would never do such a thing.

Evans had been one of the first high-profile UFC fighters to train under Jackson, joining the camp after his stint on the second season of The Ultimate Fighter in 2005 at the invitation of Keith Jardine. Since then the camp has become one of MMA's most legendary.
