UFC 145: Jones vs. Evans was a mixed martial arts event held by the Ultimate Fighting Championship.

It was the 9th UFC event of the year, and took place on April 21, 2012 at the Philips Arena in Atlanta, Georgia.

[5] However, in mid-January 2012, it was announced that the event was shelved due to inability to secure a championship fight, stemming from "scheduling complications".

Being in the same weightclass, and a long-time member of Jackson's MMA, the UFC veteran Evans naturally took the young and inexperienced fighter Jones under his wing.

[9] At UFC 128 (March 19, 2011), Evans was expected to fight for the Light Heavyweight title against then-champion Mauricio Rua.

Shortly afterwards, Jones stated in an interview with MMA reporter Ariel Helwani he would be willing to fight Evans if the UFC asked.

[10] Since UFC 128, Jones had defended his championship twice against former champions (Quinton Jackson and Lyoto Machida).

[13] Matt Wiman was expected to face Mark Bocek at this event, but was forced off the card with an injury and replaced by the returning John Alessio.

He was fined 20 percent of his purse, and his fight with Anthony Njokuani became a catchweight bout at 158 lb.

In the first round, Wisniewski clinched and dragged Clements to the mat, and passed to full mount.

With two minutes left in the round, referee Fernando Yamasaki issued a controversial stand-up order.

After a close second round, Clements controlled the third, landing powerful right hand punches and dropping Wisniewski with a knee.

[16] The fourth match pitted Anthony Njokuani against taekwondo fighter John Makdessi.

The third round was more of the same until the horn sounded, and all three judges scored the bout 30–27 for the winner by unanimous decision, Anthony Njokuani.

[16] In the sixth bout of the evening, heavyweights Travis Browne and Chad Griggs squared off.

Browne easily transitioned into the full mount position and quickly secured an arm triangle choke.

In the final round, Bocek transitioned to full back mount from a body triangle on Alessio.

Hominick continued to land punches throughout the round, and both fighter's faces were bruised and bloody by the end.
