He added another win to his record after a Unanimous Decision victory and bringing his streak up to 6 fights before fighting on an actual UFC card at UFC Fight Night 140. His streak continued to grow, as he got a huge first-round knockout victory where he took out Khalil Rountree with a vicious elbow within 1 minute and 57 seconds of the fight starting.
He is no stranger to 1st round stoppage wins, having secured 11 of them throughout his career. Given his attitude, he is likely to go quite far in the UFC and this is something to watch out for in 2019.
