Watch: 46 year old Roy Jones Jr. should probably call it quits after this vicious KO

Roy Jones Jr. has been fighting a long time.

The 46 year old will go down as one of the greatest boxers ever, but is currently well past his peak, as tonight's fight against Enzo Maccarinelli showed. The cruiserweight pair fought in Moscow in a non-title bout, and although it didn't last long, there's a clear argument to suggest it never should've went ahead at all. The Welsh fighter stopped his opponent with a vicious KO after just four rounds, and hopefully this is the last fight for the a four weight world champion. Jones, a veteran of 71 professional bouts, should probably hang up the gloves after this. Tough to watch. https://twitter.com/S_HASHMEE/status/675780259216773120 https://twitter.com/BoxingBritain1/status/675779896011055104
