Sheldon and two Birmingham team-mates, Dean Lyness and Ashley Sammons, were selected for the England under-17 squad for the Nordic Tournament in Denmark in July and August 2007.[7] He played in all three group matches, and scored from 20 yards (18 m) in the 2–1 win against Finland, but losing to Sweden meant they failed to qualify for the final.[8] Sheldon scored again as England beat Norway 4–1 in the third-place play-off.[9]
During his scholarship, he played both youth and reserve-team football, and was a first-half substitute in the Birmingham City team, a mixture of youth and first-team players, that beat Burton Albion 5–0 in the final of the 2008 Birmingham Senior Cup.[10] The following year, he was a regular in the Birmingham youth team that reached the semi-final of the FA Youth Cup, in which they lost over two legs to Liverpool's youngsters.[11] Only one of his age-group was offered a professional contract; the others, Sheldon included, were released.[12]
Sheldon joined Conference North (sixth-tier) club Redditch United for the 2009–10 season. After six months and six goals, he left in January 2010 to take up the offer of a professional contract with Slovenian PrvaLiga team Interblock of Ljubljana.[13] He played twice for Interblock in the Slovenian Cup, and made ten appearances (seven starts) in the 2009–10 PrvaLiga,[1] at the end of which the team were relegated[14] and Sheldon returned to England.
Sheldon signed for Stratford Town in October 2013. After missing only one match between then and the following September, he completed the 2014–15 season with Sutton Coldfield Town, helping them gain promotion to the NPL Premier Division. He rejoined Stratford Town, made 52 appearances in all competitions during the 2015–16 season, and took his total past the 100 mark in August 2016, marking the occasion with a "trademark long-range special", before leaving the club in November for off-field reasons.[22] Sheldon spent a couple of months with Hednesford Town, scoring once from nine Northern Premier League matches,[23] and in February 2017, signed for Chasetown.[24]
Sheldon played seven matches in the NPL Division One South and scored twice,[25] before suffering an ACL injury in March 2017. He underwent reconstructive surgery some months later. Soon afterwards, he was diagnosed with testicular cancer. He received surgery and chemotherapy at the Queen Elizabeth Hospital, Birmingham,[26] and in March 2018 was reported to be in remission.[27]
