Looks like we have our answer.
The question was, "Why can't Melvin Guillard return to Jackson's MMA in Albuquerque, New Mexico?" The Ultimate Fighting Championship (UFC) lightweight left on what he says were "good terms" back in early 2012, but this report said his request to join his former teammates was denied.
MMA Junkie explains why:
According to Bernalillo County (N.M.) court records, Guillard currently faces five charges: two misdemeanor counts of aggravated battery, to which he pled not guilty. Three misdemeanor counts of failure to appear in court were settled. A jury trial on the assault charges is set for April 10, where he faces six months in jail for each count, in addition to fines and probation.
Sounds like Melvin's next fight will be in court.link
