On Wednesday afternoon, during a press event in Las Vegas, UFC president Dana White announced MacDonald had finally secured his long awaited number one contender’s position and will now face reigning UFC welterweight champion Robbie Lawler at UFC 189 in Las Vegas. MacDonald (18-2), a Montreal native, was scheduled to meet Hector Lombard in the co-main event at UFC 186 before it was revealed Lombard tested positive for the anabolic steroid desoxymethyltestosterone in a post-fight drug test following his Jan. 3 win over Josh Burkman at UFC 182. As a result he was pulled from the bout. Prior to this change in opponents, MacDonald earned a violent third round knockout over former Strikeforce champion Tarec Saffiedine in their main event matchup at UFC Fight Night 54 in October.

In hist most recent bout, ‘Ruthless’ was seen walking away with his belt after coming out on top against former champion Johny Hendricks in their second meeting at UFC 181 in December. Lawler had lost their initial contest at UFC 171 last March. He would go onto score back-to-back victories over Jake Ellenberger and Matt Brown, thus earning his rematch with Hendricks, before getting his revenge in the former of a hard-fought split decision victory.
