It is going to be a good week for the Murray family as Joe's brother John has been preparing for his lightweight English title bout with Dean Hickman by taking in some quality sparring.
John is sparring with Ricky Hatton three times this week, the first session was Monday, and he hopes that sparring with a world Champion will prepare him for anything that Hickman can produce.
Murray will take part in up to eighteen rounds of action with Hatton over the course of the week. Monday's session went well. Hatton was said to have been impressed by the strength and skill of Murray. Hatton is preparing for a December 8th clash with Floyd Mayweather but felt that he could incorporate assisting Murray into his own training regime.
