He claimed his first professional title on 30 March 2019, winning the vacant WBA International super-welterweight belt thanks to a split decision success over Anthony Fowler in Liverpool.[9][10][11]
In early 2020 he spent 12 days in rehab at Tony Adams’ Sporting Chance Clinic in a bid to tackle problems with gambling, drugs and alcohol.[14] Fitzgerald vacated his British title due to his personal issues and having served time in prison on remand following his arrest for an alleged assault and subsequently admitting a charge of breach of the peace at Preston Magistrates' Court in November 2020.[15][16]
He returned to the boxing ring on 1 May 2021 at Manchester Arena where he defeated France's Gregory Trenel via third-round stoppage.[17][18]
In February 2022, Fitzgerald appeared at Preston Magistrates' Court where he admitted assaulting his girlfriend and was sentenced to an 18 month community order which included completing 30 days of rehabilitation activities to address his substance misuse and anger problems as well as being ordered to carry out 40 hours of unpaid work and pay a total of £180.[19]
Fitzgerald was sentenced to 46 weeks in prison in May 2023 after pleading guilty at Preston Crown Court to causing grievous bodily harm relating in a fight outside a pub on 22 November 2022 during which he broke a man’s jaw although he was released from custody soon after the court hearing due to having already spent six months behind bars on remand.[20][21][22] The following month he was fined £150 at Preston Magistrates' Court after admitting two assault charges relating to an incident at a different pub on 13 November 2022.[23][24]
In February 2024, Fitzgerald told the media he wanted to relaunch his boxing career after he was found not guilty of rape following a trial at Preston Crown Court stemming from an allegation for which he was first arrested in April 2020.[25][26][27]
