Jon Jones submits Lyoto Machida at UFC 140

Jon Jones expressed emotion, shoulder-shimmying and yelling once inside the octagon. That was something we're not used to seeing from the UFC light heavyweight champion.

Jon Jones was sent staggering backward after catching a left hand to the face from Lyoto Machida. That was something we're not used to seeing from the UFC light heavyweight champion.

Jon Jones had his hand raised in victory at UFC 140 in Toronto on Saturday night. That is something we are used to seeing from the UFC light heavyweight champion.

Jones used a standing guillotine choke to submit Machida with 32 seconds left in the first round to successfully defend his title for a second time. Only four of the 11 UFC light heavyweight champions have ever done that.

"He didn't have me hurt but he did punch me pretty good and had me wobbling," Jones said. "He was definitely a tough puzzle."

To say Jones (15-1) has won six straight fights is slightly misleading. The only loss on his record was by disqualification against Matt Hamill.

Machida (17-3) scored points in the first round by connecting with several solid left hands, mainly by countering off left leg kicks from Jones.

Tentative in the first round, Jones became more aggressive in the second round as he used his wrestling background. Jones, the 2005 New York State high school wrestling champion, took down Machida with 2:20 left. Once he scored the takedown -- on his first attempt of the fight -- Jones landed a huge elbow that opened up a cut on Machida's forehead.

Referee John McCarthy called timeout with 1:33 left to have the doctors look at Machida's cut. He was deemed OK to continue fighting, and McCarthy returned the fighters to the same position with Machida pressed up against the cage in a clinch with Jones.

"I know Lyoto is a black belt so I was expecting a lot more motion from him," Jones said. "But he wasn't doing much."

The two fighters eventually separated. They exchanged punches simultaneously, with Machida on the wrong side of a left hand from Jones. Machida, former champion who has lost three of his last four fights, fell to the ground and Jones moved in.

Machida got back to his feet but found himself in a standing guillotine choke. Jones had Machida's neck cranked toward his right shoulder. Machida's right arm went limp, and McCarthy stepped in to stop the right.

Once Jones let go of the choke, Machida went tumbling to the ground and didn't even try to brace his fall. He was completely out.

"It's not really a move that I practice," Jones said. "I think it's just something that comes natural from my wrestling."
