The Ultimate Fighting Championship today announced the full card for UFC 115, which takes place June 12 at GM Place in Vancouver, British Columbia, Canada. But there's one loose end that needs to be tied up: Thiago Alves vs. Jon Fitch.

The promotion did not announce the long-awaited rematch because the New Jersey State Athletic Control Board has not yet cleared Alves, who was suspended two days before a scheduled meeting with Fitch at March's UFC 111 event due to a failed CT scan and subsequent brain surgery, to fight.

Alves (16-6 MMA, 9-3 UFC) will return to New York April 21 to get medical clearance to fight Fitch (22-3 MMA, 12-1 UFC) on June 12, his representatives told MMAjunkie.com (www.mmajunkie.com). If all goes well, an official UFC announcement will follow.

As MMAjunkie.com previously reported, Alves underwent surgery on March 31 to correct an arteriovenous fistula on the left side of his brain. The NJSACB first caught the problem during the fighter's medicals for UFC 111 and pulled him from the card while arranging a visit with a New York-based neurointerventionalist for treatment.

An arteriovenous fistula occurs when there is an abnormal connection between an artery and a vein and can be congenital, created by surgery, or caused by disease. After the procedure, which was minimally invasive and separated vessels that had crossed inside Alves' brain, the fighter was told he could return to training in three weeks.

Alves did as he was told but didn't stay dormant for very long.

"He started running two days after getting out of the hospital and feels great," Dan Lambert, an Alves representative, told MMAjunkie.com today via text message.

If the 26-year-old Alves gets a clean bill of health from the New York-based neurointerventionalist, the results will be passed to NJSACB officials, who will then make a final decision on whether to return him to active status.

Malki Kawa, Alves' agent, feels confident the final step is just a formality.

"He should be good to go," Kawa said.

The American Top Team fighter had not competed since a five-round decision to welterweight champion Georges St-Pierre at UFC 100 in July 2009. Alves has twice been scheduled to avenge a second-round TKO loss to Fitch, which came in 2006. A knee injury forced him out of UFC 107 in December, and the failed CT exam once again had "Pitbull" on the sidelines.

Fitch, meanwhile, ended up fighting late replacement Ben Saunders at UFC 111 and won a lopsided unanimous decision. The longtime contender has now won 12 of his 13 UFC fights; the lone loss came to champ St-Pierre at UFC 87. The American Kickboxing Academt fighter has gone to a decision for his past six wins, including all four in his recent win streak, though he's faced tough-to-finish opponents such as Mike Pierce, Paulo Thiago and Diego Sanchez.

UFC president Dana White posted a Twitter message soon after Alves' surgery saying the Fitch fight was slated to take place at UFC 115.

If Alves is cleared and the Fitch rematch booked, a current UFC 115 main-card fight – such as Carlos Condit vs. Rory MacDonald or Evan Dunham vs. Tyson Griffin– could be demoted to the preliminary card to make room.
