TDA 2017 Rules
Rule #7: Alternates, Late Registration, & Re-Entries
A: Alternates, players registering late, and re-entries will be sold full stacks. They will randomly draw a seat and table by the same process and from the same seat pool then in place for new players and are dealt in except between the small blind and button.
B: In re-entry events, if a player is permitted to forfeit chips and buy a new stack, the forfeited chips will be removed from play.
