LAS VEGAS – Gordan Ryan praised UFC heavyweight champion Jon Jones ’ ability to learn, comparing him to a fellow all-time great. Ryan spent some time training with Jones (27-1 MMA, 21-1 UFC) ahead of his scheduled first title defense against Stipe Miocic last month, which ended up getting canceled after Jones tore his pectoral muscle before UFC 295. Ryan, a jiu-jitsu black belt and multiple-time grappling world champion, said Jones reminds him of UFC Hall of Famer Georges St-Pierre .
