Welsh Under-21 international Mark Peters was unable to make the grade at Manchester City and so joined Norwich in 1992. However the same situation arose and it was not until he transferred to Peterborough the following season that he gained regular first team action.

He joined Third Division Mansfield in 1994/95 and became a favourite with the Stags' fans. Injuries forced him to miss most of the 1996-97 season. He regained his place in the Mansfield side in the autumn of 1997 only to suffer a fractured skull. He returned to first team action in March 1998. These injuries limited him to only 108 games for the Stags in which he scored 9 goals. Mark was released by Mansfield at the end of the 1998/99 season and joined Conference side Rushden & Diamonds.

His form won him a call-up for the Welsh semi-professional side in February 2001 and was instrumental in Rushden's Conference title that was won on May 1st 2001. Two seasons later and Mark was playing a role as the Diamonds were promoted to Division Two. However Diamonds obviously felt that Mark would not make the grade in Division Two and granted him a free transfer. This materialised in September 2003.

Once freed, he signed for Leyton Orient on 12th September and made his debut in the 0-0 draw with Lincoln the following day. Former Posh players Marcus Ebdon and Greg Heald were instrumental in persuading their former Posh teammate to join them at Orient.

Out of the Orient first-team during hte 2004/5 season, Mark joined Aldershot on loan on 11th November 2004. He returned to Brisbane Road but was released at the end of the 2004/5 season. He returned to Aldershot in July 2005 on pre-season trial playing in a friendly against Farnborough. He later trialled with Cambridge United and signed for them at the end of July 2005.

Now acting in a player-coach role, Mark signed a one year extension to his contract in June 2007.

In late May 2008, Cambridge announced that Peters' contract would not be renewed along with Courtney Pitt, Leo Fortune-West, Dan Chillingworth and Michael Hyem. Age appears to have been a factor in Peters' release as Cambridge manager Jimmy Quinn, reflecting on United's Conference play-off final defeat to Exeter, said "I think where we need to go forward now is to get some of the younger players in and around the team. You look at Exeter's team and you look at Aldershot's team and they've got a lot of young players."

Peters quickly signed for Conference South newboys Kings Lynn. After a successful season with the Linnets, Peters left when new manager Carl Heggs had no need for him and he moved to St Albans City where he will be Player/Assistant Manager as well as coaching the youth team.

He later joined Corby Town as Head of Youth and for a while was interim manager.

In June 2015 Peters returned to Mansfield as Head of Academy Coaching.

He returned to Corby as manager in February 2020 but left at the end of the season.
