Top light heavyweights Alexander Gustafsson and former pound-for-pound number one Jon Jones recently got into a heated exchange on social media.
Things kicked off when 'The Mauler' said Jones wasn't a 'good person' or a true champion after his brutal TKO victory over Glover Teixeira at UFC Stockholm last month.
'Bones', who beat Gustafsson via decision in a five-round championship epic at UFC 165, fired back by calling Gustafsson a 'dork' with no 'heart'.
Things continued to escalate from there, and Gustafsson insinuated that Jones only won at UFC 165 because of the lack of USADA drug testing at the time.
