situation had cleared up, and this allowed Mason to link up with Wanderers until the New Year on a similar arrangement to that of teammate Kevin McNaughton. He made his Bolton debut on 30 November 2013 in an away defeat against Middlesbrough at the Riverside Stadium as a substitute for Neil Danns. His first start and goal came a week later as he opened the scoring for Wanderers in a 3–0 win over Doncaster Rovers at the Reebok Stadium. On 20 February 2014, Mason re-joined Bolton Wanderers on a two-month loan, but returned on 11 August 2014 for a full season-long loan. On 16 September 2014, Mason scored a second half hat-trick to earn Bolton their first win of the season at home to Rotherham United. This was the first hat-trick scored by a Bolton player in a competitive match since Fredi Bobic against Ipswich in 2002. On 21 January 2015 his loan was terminated by mutual agreement. Return to Cardiff Following his return from injury, Mason became a key part in new Cardiff boss, Russell Slade's plans towards the end of the 2014–15 season. The next season, Mason was rewarded the number 10 shirt and started the first 17 games of the season, with a return of 5 goals. During October, Cardiff suffered a barren run of goals scoring only 2, one where Mason scored the opener in a 1–1 with Brighton & Hove Albion. This resulted in Mason being dropped and new signing Tony Watt taking his place. Wolverhampton Wanderers On 28 January 2016, Mason signed a three-and-a-half-year contract with fellow Championship club Wolverhampton Wanderers for an undisclosed fee. He made his debut for Wolverhampton Wanderers on 2 February 2016 against Bolton, in a 2–2 draw at Molineux, in which he scored after three minutes of the game. The following season saw him score four further goals (including against Midlands rivals Birmingham and Aston Villa), to add to the three for Wolves in the second half of the previous campaign. However, after another new head coach arrived -–the fourth different one at Wolves within his short spell – Mason found himself out of his plans. On 23 August 2017, he was sent on loan to fellow Championship side Burton Albion until January 2018. He scored on his debut for Burton in a 1–1 draw with Sheffield Wednesday on 26 August 2017. After returning from his spell at Burton,
