"The victim of the crime does not wish to return to the United States and prosecute this case", prosecutor Khalil Madani said, per the Miami Herald.
Officials had charged McGregor with strong-armed robbery and criminal mischief in the case, saying he "knocked" the phone from Abdirzak's hand outside Miami's famous Fontainebleau Hotel while he and others took video of the fighter.
McGregor was not in court for today's brief hearing.
In addition to the criminal charges against McGregor, Abdirzk also filed a civil suit, suing McGregor for $15,000.
A trial was due to go ahead on Monday at Miami-Dade County Court but the court's online system has recorded "nolle pros" next to the charges and the case will not proceed.
Abdirzak, a resident of England, later dropped his lawsuit after reaching an out-of-court settlement with McGregor. "I don't know what it cost him, but I'm sure it worked out for him". He agreed to a plea deal and avoided being deported from the U.S.
Later that month, The New York Times reported McGregor was under investigation for an alleged sexual assault in his native Dublin in December.
McGregor announced his unexpected retirement from mixed martial arts earlier this year but has since appeared to recant this several times on social media in recent months. Although he retired in March, he's been filmed training since. The rivals brawled in the cage immediately afterward, prompting the Nevada Athletic Commission to suspend them both.
