Jersey Flegg Cup
The Jersey Flegg Cup returned in 2019, with the NSWRL reviving the historic competition following the cessation of the NRL-run Under 20s National Youth Competition.
The competition is named after Harry “Jersey” Flegg, who played for the Eastern Suburbs in 1908 and 1909, and was a prominent administrator of the game up until 1960.
It began as an Under 19s age group until the NRL was formed in 1998, and was originally held as part of the NSWRL’s junior representatives season that was played over 9-12 weeks early in the season.
The Jersey Flegg Cup reverted to an Under 21s men’s competition in 2021, spanning a 26-week season which runs in tandem with The Knock-On Effect NSW Cup. The competition now consists of 14 NSWRL clubs, including 11 NSW-based sides, the Melbourne Storm, Warriors and Kaiviti Silktails.
In 2026, Penrith Panthers defeated Canterbury-Bankstown Bulldogs 62-16 to reclaim the Jersey Flegg Cup for the first time since 2022.
