Adam Henry Chapman (born 29 November 1989) is a Northern Irish professional footballer who plays as a midfielder for Retford United. Born in Doncaster, he started his career with Sheffield United but failed to break into the first team and was loaned to Oxford United before joining them on a permanent basis in 2009. Chapman served a prison sentence in 2010 after being found guilty of causing a death by dangerous driving but rejoined Oxford on his release. He was subsequently loaned to Newport County and Mansfield Town before joining Newport on a permanent basis in 2013. He signed for Mansfield Town on a permanent basis for the 2015–16 season, playing for one season before moving into non-league football. Career Scouted by Sheffield United as a youngster, he went on to sign a professional deal with the club in the summer of 2007. He established himself as a regular in the reserve side, while also captaining the team. In January 2009, he joined Oxford United of the Conference Premier on a month's loan, which was later extended to the end of the 2008–09 season. He scored a 68th-minute free-kick in the 1–0 victory over Burton Albion in the penultimate game of the season, which prevented Burton winning the league until the final day. In March 2009 Chapman indicated that his future could lie away from Sheffield United, and that it was up to them to decide his future at the end of the season. After failing to break into the Blades' first team he signed for Oxford United at the end of the 2008–09 season for a fee of £15,000 with a 50% sell-on clause. Chapman was named Man of the Match in Oxford's Football Conference play-off victory at Wembley on 16 May 2010, while awaiting sentencing for causing death by dangerous driving. Shortly after his return to Oxford United in September 2011, he sustained an ankle injury in a friendly game. He made his first first-team appearance in the Football League as a late substitute against Morecambe on 10 December 2011.
