UFC fans will be treated an action-packed card full of intriguing fights. The main event will see two former light-heavyweight champions, Lyoto Machida and Quinton 'Rampage' Jackson, square off and look to bounce back into the 205lb tile picture. The co-main event will see BJ Penn and Mat Hughes collide in a profliic bout to end their trilogy, and it will certainly answer a lot of questions about the future of both competitors.

In a lightweight bout, submission artists Georges Sotiropolous and Joe Lauzon will meet, with the winner likely receiving more competitive fights. While middleweight Gerald Harris and light-heavyweight Phil Davis will look to earn a win within their respective divisions.

Here are some things to expect at UFC 123.
