From the AFL website:
----------------------Carlton has received a massive draft boost heading into 2026, with next year's potential No.1 pick Cody Walker informing the club this week that he intends to nominate the Blues under father-son rules.
Walker, whose father Andrew played 202 games for Carlton, had also been eligible to join Richmond as part of its Next Generation Academy program.
However, AFL.com.au understands the highly rated teenager told both Carlton and Richmond officials earlier this week that he intends to head to Ikon Park as part of next year's draft where he will follow in his father's footsteps.
Walker, who is Indigenous, had qualified for the Tigers as a Next Generation Academy member given he lives in Echuca, which sits within the club's Sunraysia zone.
