BJ, that's for the mid season upgrade, which I believe is open to all rookies, however the pre season upgrade must come from Cat A list to prevent a club starting the season with more than 44 listed players (senior/Cat A rookie lists).
Yep, but the wording is the same for all rookie upgrades, its just that the section is much longer.
The Rules in relation to upgrades make no distinction between Cat A and Cat B rookies
But here it is anyway:
10.11 Inclusion of Rookie List Player onto Primary List
(a) Prohibition – Playing in AFL Competition
A Player included on a Club’s Rookie List shall not play for the Club in the AFL Competition except for the Pre-Season Competition.
(Refer also Rule 5.7)
(b) Primary List
A Club may apply to the AFL to transfer a Player or Players from its Rookie List onto its Primary List:
(i) on the day when its Primary List is lodged with the AFL prior to the National Draft Selection Meeting under Rule 6.1 by lodging with the AFL the form prescribed in Schedule 1 as Form 33. In which case, the Club shall forfeit its last selection or, if more than one player, its last and each previous draft selection at the National AFL Draft Selection meeting.
(ii) under Rule 26.1(b); or
(iii) at any time between the National Draft Selection Meeting and the day when its Primary List is lodged with the AFL prior to the Pre-Season Draft Selection Meeting under Rule 7.1, if a Player’s name has been deleted from that Club’s List under Rule 7.6 by lodging with the AFL the form prescribed in Schedule 1 as Form 33.
(c) Primary List during AFL Season
A Player included on a Club’s Rookie List shall not be promoted onto the Primary List of an AFL Club during the Home and Away Matches or while it continues to compete in the Finals Series save and except under Rule 26.1(b) or where an AFL Club demonstrates to the AFL that there are exceptional and compelling circumstances that make it harsh and unconscionable for a Rookie not to be promoted onto that AFL Club’s Primary List and where to do so would not result in that AFL Club exceeding the maximum number of Players on its Primary List.
(d) Maintain Primary List
Where a Club applies to the AFL to transfer a Player from its Rookie List onto its Primary List in accordance with Rule 10.11(b), it must de-list a Player from its Primary List if that is necessary to ensure that the Club does not exceed the number of Players it is able to retain on its Primary List as required under Rule 5.3.
