Perhaps nobody in the UFC's middleweight division owns more reason to be upset with Yoel Romero's potential drug-test violation than Ronaldo Souza.

"Jacare" faced Romero at UFC 194, dropping a split-decision to the former Olympian. The loss marked Souza's first since March 2012 and at the time seemed to derail his UFC title chances.

Now, after Romero became the latest fighter to come under fire from the U.S. Anti-Doping Agency, Souza's manager, Gilberto Faria, has a new plan in mind for his client.

"With doping or not, Jacare won that fight," Faria told MMAFighting.com's Ariel Helwani. "Nothing will be more fair than Jacare versus Luke Rockhold next."

Immediately following the Dec. 12 event in Las Vegas, Romero certainly looked the part of the number-one contender for champion Luke Rockhold's middleweight title. This, however, changes in light of the recent news.

Former middleweight champ Chris Weidman recently told Helwani he wants a second crack at Rockhold, while 38-year-old Brazilian Vitor Belfort also lurks just on the horizon. Belfort is 4-1 in his last five, and he's the last man to defeat Rockhold inside the cage, finishing the current champ via spinning heel kick at UFC on FX 8.

Now, with Souza re-entering the sweepstakes as well, murkiness reigns in the UFC's middleweight division.
