CONCACAF has announced a number of changes to its Gold Cup regulations ahead of 2013's upcoming tournament, the most notable of which include a provision for teams to amend their roster after the group stages and new tiebreaker rules.
One of the key changes brought into effect is a rule that allows teams to swap up to four players from their 23-man roster for up to 24 hours after the conclusion of the group stage. The four new players still must come from a 35-man list of players that competing teams are required to submit 45 days prior to the tournament and must draw upon for their final 23-man roster.
The other key change involves the tiebreakers for the group stage, with goal differential across taking precedent over head-to-head record between the two teams when determining who advances from group play. There are three groups of four, with the top two teams in each group and the two best third-placed teams advancing from the group stage to the final.
