O'Neill is returning to rugby league in 2025 after a spell away from the game.

After starting playing as a youngster at Askham, the Barrow born O’Neill progressed through the Academy at Castleford Tigers before making his Super League debut in 2019.

In 2021, he was selected for the England Knights Performance squad.

Across three seasons in Super League, he made 29 appearances before being released from his contract with the Tigers in 2022, to allow him to appear on the ITV reality show, Love Island.

He returned to Castleford in 2023, before being released at the end of the season.
