The lightweight bout between Gray Maynard and Nate Diaz tonight at “UFC Fight Night 20” just got a lot less interesting as it appears Frankie Edgar will get next dibs on BJ Penn’s UFC 155-pound crown.

Edgar is riding a three-fight winning streak and stakes claim to a dominating 11-1 mark, 7-1 inside the Octagon. As impressive as that may be, guess who handed him his only professional blemish?

Gray Maynard…

That’s right, the same Gray Maynard that holds a perfect 8-0 record, but most importantly, out wrestled Edgar to an easy unanimous decision in their meeting at “The Ultimate Fighter 5 Finale” back in June 2007.

So Josh Gross of SI.com, you’re telling us that even IF the Xtreme Couture-trained fighter steamrolls Diaz this evening, Edgar has already earned himself the 5Round affair, leapfrogging the man that schooled him?

“Edgar’s management said nothing was done, and Maynard’s performance could determine opponent,” Gross told us. “I’m hearing it’s Edgar regardless.”

One could argue that Edgar’s resume is slightly more credible than Maynard’s as he posts W’s over the likes of former champ Sean Sherk, Spencer Fisher and Maynard’s teammate Tyson Griffin; while “The Bully’s” most notable wins are over Roger Huerta, Jim Miller, Rich Clementi, POSSIBLY Diaz, but most importantly Edgar,

However, doesn’t a head-to-head win end the conversation?

It’s believed Penn will meet Edgar/Maynard at UFC 112 in Abu Dhabi.
