Wardrop started his career at
Celtic, and captained the club's
Under-20s to victory in the 2017
Scottish Youth Cup final. On 1 August 2017, Wardrop joined
Scottish Championship club
Dumbarton on loan, until May 2018. He scored his first senior goal, the winner, against
Inverness Caledonian Thistle in September 2017. Wardrop signed a two-year contract with
Dundee United on 31 May 2018. After suffering an injury that ruled out a potential loan return to Dumbarton in January 2019, he rejoined the club on loan in January 2020 playing seven times prior to the season being ended early by the
COVID-19 pandemic. Wardrop was then released by United in May 2020 and signed a permanent contract with Dumbarton. He left the club after one season in June 2021 and subsequently signed a one-year contract with
Airdrieonians but left just two months into the season for personal reasons. In 2024, after documenting his return to professional football on social media, he agreed a deal with Swedish
Ettan Fotboll club
Ljungskile SK. == International career ==
