UFC pound-for-pound greats Jon Jones and Anderson Silva engaged in a two-hour long sparring session at UFC Headquarters in Las Vegas, Nevada on Monday.

After UFC’s “The Tmie Is Now” press conference (which you can watch in full here), “Bones” Jones and “The Spider” sparred, with Silva calling Jones a “f*cking crazy guy.”
