UFC on FOX 5 Results: Josh Koscheck Calls out Rory MacDonald

Former UFC welterweight title challenger Josh Koscheck has fought some of the best in the world, so it should come as no surprise that he called out Rory MacDonald moments after his win over BJ Penn on Saturday. 

Koscheck tweeted: 

"

Maybe Roy should fight me??? I Doubt the UFC would want to see him get his ass kicked.

At UFC on FOX 5, "Ares" battered Penn for 15 minutes, nearly stopping the UFC legend on several occasions in the second round.

Speaking to UFC color commentator Joe Rogan right after the bout, MacDonald made it clear that he wants a rematch with Carlos Condit next. 

After taking a beating for two rounds, "The Natural Born Killer" rallied back in the third, stopping MacDonald with just seven seconds left in their "Fight of the Night" performance at UFC 115 in June 2010.

Since then, MacDonald has battled back to win four straight inside the Octagon.

Meanwhile, Koscheck is 2-2 in his past four, most recently losing a hotly-contested split decision to Johny Hendricks at UFC on FOX 3 in May. 

In October, Koscheck said he wanted to fight former Strikeforce welterweight champion Nick Diaz at UFC 157, scheduled for Feb 2, but the bout never came to fruition since Diaz is still serving a suspension issued by the Nevada State Athletic Commission. 

Which fight makes more sense for MacDonald next: a rematch with Condit or with a new, yet still tough, opponent in the form of Koscheck?
