Personally, I think he's already lost that chin. Look at his fight with Mendoza. When he fought Taylor, he looked like he was very conscious of protecting his chin. A Lacy who can't rely on his chin is basically castrated.
100 percent the fight just ended , but the great thing is the Stars have all aligned , it's time for Jones-Hopkins! so Hopkins can further his great resume!
Jones was very close to giving a good old fashioned on the canvas KO to Lacy. At the very end it looked like Lacy asked him to take him seriously, then Jones asked him if he was sure, Lacy confirmed and then they touched gloves. Jones then threw some big punches before the bell rang and the fight was stopped.
