Career
Doidge started his career in the youth system at Southampton where he spent three years before he was released after the club thought he would not be tall enough as a centre forward. He then joined Bristol Rovers for two years, but failed to earn a youth scholarship and was released in 2008 at the age of fifteen. In November 2011 he joined Welsh Football League First Division side Barry Town, going on to score sixteen goals in sixteen games in his maiden season for the club
In his second season for the club he netted ten times in fourteen appearances, including a hat-trick against Goytre United which propelled Barry to the top of the table.
In January 2013, he signed for Welsh Premier League side Carmarthen Town. During his time with Carmarthen, he scored nineteen goals in forty-three appearances.
In April 2014, he joined Football League Two side Newport County on a week trial, however no move materialised. In July 2014, he joined League Two side Dagenham & Redbridge on trial, scoring in pre-season friendlies against Tottenham Hotspur and Billericay Town.
Dagenham then pulled out of a deal to sign Doidge after discovering they would have to pay a fee to Carmarthen, having believed the striker would be available on a free transfer.
A deal was eventually agreed in August for an undisclosed fee, with Doidge signing a two-year contract, having also turned down an offer to sign for Conference Premier side and former club Bristol Rovers. Shortly after signing for the Daggers, he suffered an ankle injury during the warm-up against Hartlepool United, which kept him out of action for a month. In September 2014, he made his professional debut in a 1–1 draw with Cheltenham Town, replacing Jamie Cureton as a late substitute.
His first professional goal came in a 3–1 defeat to Luton Town, scoring a consolation after coming on as a substitute.
He struggled to retain a place in the first team and in January 2015 he was sent on loan to Conference Premier side Dartford on a one-month loan, to regain his fitness. He made his debut in the 6–1 away defeat to Dover Athletic.
Whilst playing semi-professional football for Carmarthen Town he worked for South Wales Police.
