The UFC inked a deal with Amir Aliakbari on Saturday, according to ESPN's Marc Raimondi.
Aliakbari, a previously unsigned top heavyweight, has won two wrestling world championships. However, a failed drug test in 2013 resulted in him being stripped of one title.
That marked his second doping penalty after he was banned from the 2012 Summer Olympics for a similar violation.
Aliakbari has won five straight MMA fights and holds a 10-1 record. His only loss came against legend Mirko Cro Cop. In his most recent fights, Aliakbari has beaten UFC veteran Daniel Omielanczuk and Shelton Graves.
