* Senior club appearances and goals counted for the domestic league only and correct as of 18 February 2016.
Guy joined Doncaster Rovers on loan during the 2004–05 season. Having impressed during his brief loan spell, scoring three goals in nine appearances, Guy signed a permanent deal with Dave Penney's side prior to the start of the 2005–06 season
Despite only scoring three goals in 31 league appearances throughout the 2005–06 season, Guy's pace and dribbling ability made him a handful for any defence, which helped him form an effective striking partnership with Paul Heffernan during the first half of the season.
The 2007–08 season seemed to bring a change to Guy's play, as he started to weigh in with vital goals and impressive performances, finishing the season with 8 goals in all competitions, his best in a season to date. Despite scoring the winning goal in the opening game of the 2008–09 season against Derby County and the opening goal in the following match against Cardiff City, he struggled to continue his positive start to the season and failed to score another goal for Doncaster. In early 2009, Guy spent a month's loan spell at Hartlepool United, but he struggled to make an impact at Victoria Park, and was sent back to Doncaster after he picked up an injury.
In 2010 he joined Oldham Athletic on loan, initially for a month, which was later extended until the end of the season. He made 12 appearances for the club, scoring 3 goals, his first for any team in any competition in over two years.
