Davidson, a product of the Port Vale youth team was handed his professional contract at the end of the 2007–08 season. By his second season he was a first team regular, he received his first sending off against Brentford for a 34th-minute slide challenge on Karleigh Osborne. He received a three match ban, but was supported by his teammates, parents and also a Vale supporting Priest who visited him in the locker room to give Davidson support. Assistant manager Ian Brightwell believed the challenge did not warrant a sending off and the club appealed the ban, to no avail. Despite being a regular in the first half of the season, he played just four games of the 2009 end. He considered leaving the game, but in June 2009 signed a new 12-month deal with the club. He joined Conference North side Stafford Rangers on loan in August 2009. At the same time he was also transfer listed by Vale manager Micky Adams, along with five other youngsters. With his prospects at Vale Park limited, Rangers were keen to extend the loan deal, after Davidson was impressive in his first six games for the club. However he instead returned to Vale Park. In December that year he joined nearby Nantwich Town on loan, a team mid-table in the Northern Premier League Premier Division. In January the loan deal was extended by a further month. In March 2010 he was informed that he would not be offered a new contract by the "Valiants" at the end of the season, and immediately re-joined Stafford Rangers on loan until the expiry of their contracts. Expected to join Rangers permanently in summer 2010, Davidson was hopeful of playing higher level football, but did however sign with Rangers. Before the end of the season he switched clubs to Hednesford Town of the Southern League Premier Division. Following defeat in the play-off final to Salisbury City and a second-place finish in the 2010–11 season, Hednesford were moved to the Northern Premier LeaguePremier Division. In summer 2011 he joined Northern Premier League Division One South club Kidsgrove Athletic. The club finished in 13th place in 2011–12. He switched to Leek Town in July 2012, before leaving Harrison Park and moving on to New Mills in December 2012. He joined Nantwich Town of the Northern Premier League Premier Division for the 2013–14 season. He later moved on to Witton Albion, before returning to Kidsgrove Athletic in November 2014. The "Grove" finished 20th in the Northern Premier League Division One South in 2014–15, 15th in 2015–16, and 12th in 2016–17. He scored two goals in the 2016–17 season. Athletic finished 18th in the 2017–18 season.
