An expected bout between veteran UFC competitors Matt Serra (9-6) and Frank Trigg (19-7) has now been confirmed for the UFC 109 event which takes place on February 6th in Las Vegas.

Meanwhile a fight between Nate Marquardt (29-8-2) and Chael Sonnen (24-10-1) which was originally predicted to be on the UFC 110 card has apparently been switched to UFC 109 according to mmajunkie.

The card is beginning to take shape after it was announced earlier this week that Randy Couture (17-10) would square off against Mark Coleman (16-9).
