Michael Keith Gregory (20 May 1964 – 19 November 2007) was an English professional rugby league footballer and coach.

He grew up in the Newtown area of Wigan, and attended St John Fisher Catholic High School.

[3] He played rugby league for local club Wigan St Patricks before turning professional, signing for Warrington in June 1982.

[5] A month later, he won his first trophy at the club, playing in the 16–0 win against St Helens in the 1982–83 Lancashire Cup final at Central Park.

[4] He played his last match for Warrington on Saturday 12 February 1994, making 222 1st team starts and 24 substitute appearances and scoring 45 tries and a total points of 176.

[8] He led the youngsters to first place in the 2002 Academy Championship, before being promoted to assistant coach for the 2003's Super League VIII.

Gregory spent three months as caretaker coach, remaining unbeaten for 11 matches and guiding the Wigan Warriors to the 2003 Super League Grand Final – becoming the first side from outside the top two to make it all the way – before being awarded the job full-time on a 2-year contract.

In 2004, it became known that Gregory had been suffering from progressive muscular atrophy, a form of motor neuron disease affecting his nerves and muscles which he had possibly contracted as early as 2001.

Ian Millward was appointed as head coach of the Wigan Warriors while Gregory was still recovering from his illness.

Maurice Lindsay said that Wigan would continue to employ and pay Gregory while he was on sick leave and wait for advice from medical advisers.

The continuing support of the fans and the players has made a horrific experience bearable and I thank you all.On 19 November 2007, having used a wheelchair for the previous year, Gregory died aged 43.
