As a result, the 31-year-old is currently being observed carefully so that he doesn't exhaust himself ahead of his title matchup against Dricus du Plessis at UFC 319:Tsarukyan said:''Khamzat’s never at 100% on fight night because he constantly overtrains...He’s now being tested daily to monitor his recovery. They have devices that show his recovery status every day...They give him more time to relax, because when you’re overtrained, you can’t work properly in sparring. We need a guy who will control this 24/7 and stop him at the right moment so he won’t overtrain.''
