The attacking midfielder joins the Sports for the rest of the 2024/25 campaign, and made his debut away at Slough Town.
Adigun, 21, joined Dagenham in the summer after his release from Charlton Athletic – where he had come through the Academy from the age of 12. He had his first taste of senior football when he joined Welling United on loan last season, scoring 2 goals and providing 8 assists in just 17 games.
He joins the Sports having previously had a loan spell at Tonbridge earlier this season – scoring on his debut against Hampton back in September.
