Welterweight phenom Rory MacDonald respectfully expressed his interest in fighting the former Ultimate Fighting Championship (UFC) two-division champion, saying that the legendary Hawaiian fighter "is a really good match up" and would "be a great opportunity."
Penn responded in kind just 24 hours later by accepting the Canadian wunderkind's challenge.
At this advanced stage of his professional fight career, "The Prodigy" has to find every potential opponent appealing in some way or another. The fact that one of the brightest and most talented prospects in the sport trains with his former nemesis, UFC Welterweight Champion Georges St. Pierre, seems to make this a pretty sweet showdown.
MacDonald recently revealed that he was nudged in Penn's direction at the behest of the UFC. He obliged simply because he wants a win as big as Penn would provide on his resume.
What's interesting is what happens if he manages to pull it off, which is entirely possible considering the current run the Hawaiian is on having won just one of his last five fights. That would give MacDonald four in a row and put him right around the top of the division.
The very same division his good friend St. Pierre is still ruler of.
That's to worry about later, though. For now, Penn vs. MacDonald is going down as the co-main event of the evening at UFC 152, which is also set to feature Junior dos Santos defending his heavyweight championship against Cain Velasquez in the headlining attraction.
