UFC champ Jon Jones done underestimating opponents By: Ben Fowlkes, USA Today Sports
"With practice winding down and sparring partners drifting toward the door, Ultimate Fighting Championship light heavyweight titleholder Jon Jones stood alone on the mat, clad in boxing gloves and shin pads on a recent morning, scanning the room for his next victim.
"Volunteers had become sparse, and for good reason. With his pay-per-view main event against challenger Glover Teixeira (22-2 mixed martial arts, 5-0 UFC) on Saturday at UFC 172 in Baltimore (10 p.m. ET) growing closer, Jones (19-1, 13-1) was kicking his training up a notch."
