Luke Croll signed for Exeter City on a permanent basis in June 2017 having had a successful spell on loan during 2016/17. He left to play for Dagenham and Redbridge. 

The former Crystal Palace youngster, who had played on loan at Harrow Borough and Plymouth Argyle, initially joined City on loan in September 2016 and played his first game for the club in a 3-2 victory at Colchester United. He made 20 appearances for the Grecians during the campaign as the club reached the League Two play-off final.

Although Luke had not appeared in the play-offs, he soon was back at City in a permanent capacity making another 31 league and cup appearances over the next two seasons.

Luke subsequently joined Dagenham and Redbridge in July 2019 and, after playing 51 league games for the Daggers, was released in May 2021 before joining Chesterfield on a short-term deal in November 2021 where he made a goal-scoring debut in the FA Cup against Southend. He was to make two further FA Cup appearances for the club, one of which came against Chelsea at Stamford Bridge. He also played nine National League games before leaving the Spireites.

In February 2023 it was reported Luke had signed for North Carolina FC in the third-tier of football in the United States. Towards the end of the same year he returned to Britain to join National League Eastleigh.
