Adelaide's 24-year wait to benefit from the father-son rule will continue beyond this season, with the Crows missing out on two potential draftees eight years after unsuccessfully pursuing Bryce Gibbs.

The Crows approached the AFL recently to clarify whether Jaidan Kappler and Brayden Maynard qualified to play for the club, given their fathers' lengthy careers in the South Australian league, but were told they could not sign either promising teenager.

While David Kappler played 290 games for South Adelaide, he did not play enough of them in time for Jaidan to be nominated by the Crows ahead of father-son bidding.

Under father-son rules, Adelaide has access to the sons of former Sturt, Glenelg, South Adelaide and Woodville-West Torrens players, provided they notched 200 games before 1990. They can also nominate the sons of Adelaide's own 100-game players.
