Main Card
GSP def. BJ Penn via TKO (corner stoppage) after round 4.
GSP started slow equalling BJ Penn in the first round, but completely worked over Penn from there. Taking down Penn multiple times and working his GnP, Penn mustered up little offence for the next 3 rounds outside of a couple jabs.
Machida def. Silva via KO (punch) at 4:59 of round 1.
Machida continued to back-peddle and pick his spots to attack, and Silva fell for it by chasing him. Machida, though not mounting much offence, he still rocked Silva quite a few times before finishing Silva 1 second before the round ended.
Jon Jones def. Stephan Bonnar via unanimous decision (30-27, 29-28, 29-28)
Jon Jones came out with a bunch of energy, taking Bonnar down and landing some nice shots. Towards the end he started to gas a bit, but was still strong enough to fight through and hold his own to take the fight.
Karo Parisyan def. Dong Hyun Kim via split decision (29-28, 28-29, 29-28)
Kim came out strong to start the bout, winning the first round 10-9 fairly easily against Karo who came back from surgery. However, Karo turned up the Heat in the second and third round to take the match.
Clay Guida def. Nate Diaz via split decision (29-28, 28-29, 29-28)
Predicted to be fight of the night, Guida/Diaz perhaps didn't live up to expectations. Guida, the fireball of energy, often found himself taking Diaz's back, but not mounting much offense from there. In fact, Diaz was able to swipe Clay's legs from under him and take Clay down, but Guida still stayed on his back and continued to not do much. All-in-all, Clay controlled much of the match and took home the win.
