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." Source: MMA Weekly
