Goran Reljic is out of his scheduled match-up with Thales Leites at UFC 90 in Chicago. Reljic’s manager, Zoran Saric, told MMAWeekly.com, “Reljic will not be able to fight on Oct. 25 at UFC 90. A back problem will force him out of a scheduled bout with Thales Leites.”

His back problems don’t sound as if they will keep Reljic sidelined for long though. According to Saric, “He will be out two to four months, nothing severe.”

Reljic is a dynamic Croatian fighter with an undefeated 8-0 record. He made an immediate impact when he debuted in the Octagon at UFC 84. Reljic faced American Top Team product Wilson Gouveia, dispatching the UFC veteran midway through the second round via TKO.

Following a hiccup named Martin Kampmann in his Octagon debut, Leites has since embarked on a four-fight winning streak, including a controversial split decision over Nate Marquardt at UFC 85.

No word of who will be tapped to replace Reljic has surfaced.

The bout between Reljic and Leites was believed to produce a likely contender for the UFC middleweight championship currently dominated by Anderson Silva, who will defend his belt against Canadian Patrick Cote in the UFC 90 main event.
