Higham joined Wigan in October 2005 after a transfer deal involving three clubs and fellow hooker Terry Newton. Higham was unable to join Wigan directly as his club, St Helens, would not sell. However, Bradford stepped in and bought Higham from Saints for £70,000 and then immediately released him to Wigan. In exchange, Wigan allowed Terry Newton to join Bradford. Higham signed a three-year deal with Wigan and commented: "It looked at one stage as though I would be playing next season at Bradford but when the opportunity to join Wigan came up at the last minute I jumped at it." At Wigan, Higham again teamed up with coach Ian Millward who he had played under at both Leigh and St Helens. Ian was however sacked by Wigan in April 2006 and Mickey, ironically, was coached by Brian Noble who was Bradford coach at the time of the "three-club transfer". Higham's contract at Wigan was not renewed, and he subsequently signed for Warrington on a two-year deal.
