After being used mostly off the bench in Belenenses' first season back in the Primeira Liga, Sturgeon made his breakthrough in 2014–15, playing 31 games and starting all but four. In the opener, on 17 August 2014, he scored his first professional goal in the sixth minute of a 3–1 away win against Penafiel,[6] and his second came on 4 April in a 2–0 victory over Moreirense F.C. at the Estádio do Restelo.[7]
In July 2018, Sturgeon moved to another top-flight team, C.D. Feirense, on a three-year deal.[10] In just his second game, he opened his account on 20 August with the only goal of a win over his former team at the Estádio D. Afonso Henriques.[11]
Sturgeon joined Polish Ekstraklasa club Raków Częstochowa on 10 August 2021, agreeing to an initial three-year deal.[15] On 1 September 2022, however, he left by mutual consent.[16]
Sturgeon returned to Portugal in September 2023 after four years away, on a contract at second-tier C.D. Mafra.[17]
