Butler signed for the Mariners from Walsall on a three month loan deal in October with a view to a permanent deal when the transfer window opens in January.

Butler's career began at Walsall where he came through the ranks to make his senior debut during the course of the 1993/94 season after earning rave reviews for his youth team displays.

Sadly, his career did not take off as predicted and after a total of 49 senior starts, 39 substitute appearances and 12 goals, he was allowed to join Cambridge United for £22,500 in the summer of 1997.

The move worked well for Butler and after notching 53 goals in just over 100 appearances, Reading paid £750,000 for his services in February 2000.

He continued in a rich vein of scoring form for The Royals - including a goal in their Play-Off Final defeat at the hands of Walsall in May 2001 - and played his part in their eventual promotion into what is now known as The Championship before linking up with Rotherham United in a £150,000 deal in August 2003.

Butler returned to Walsall in July 2006 and helped in the Saddler's promotion to League One last season - including scoring all three of the Saddler's goals against the Mariners.
