Father-son prospect Bailey Rice is set to choose his preferred side within the next fortnight.
Rice, the son of former St Kilda and Carlton veteran Dean Rice, has trained with both clubs throughout the 2015 season, and is one of very few father-son candidates to have multiple destination choices.
It is believed the Saints has shown more interest in the speedy half-back, but Rice's lifelong following of the Blues could strongly influence his final decision.
He played for Carlton's VFL affiliate side, the Northern Blues, in early August; many saw this as the strongest argument in his case for Carlton.
The 18-year-old defender played for the Dandenong Stingrays in the 2015 TAC Cup season, as well as Vic Country in the NAB Under-18 Championships.
He has shown a large amount of potential, being named one of the Stingray's best in their preliminary final loss to the Eastern Ranges.
Rice has the unique ability to nominate both St Kilda and Carlton, however his first preference will have to pass in order for his second to have any chance of signing him.
The NAB AFL Draft will be held in Adelaide on November 24. The Pre-Season and Rookie drafts will commence on November 27.
