They are very low on the list of issues created by Hurricane Matthew's travels in the Caribbean (Haiti has postponed an election as a result of the storm's impact on the country), but both Jamaica and Haiti have postponed their October 5 Caribbean Cup qualifiers.
New dates have yet to be set. In both cases, it is difficult to see how the matches can be played in the present FIFA window for international games. The window closes on October 11. Jamaica's October 5 opponent, Suriname, is due to play Guyana on October 8; the Reggae Boyz play Guyana on October 11. Haiti's federation has announced Les Grenadiers will be traveling to Florida for a four-day camp before their October 11 game in St. Kitts.
Short of leaving all four national teams affected (Jamaica, Haiti, Suriname and French Guiana) shorthanded by playing the games outside the FIFA-mandated windows for internationals, it would appear most likely that the matches will have to be played during the November FIFA window. That will in turn impact the Caribbean Cup fifth-placed playoffs that were due to be played between November 9 and 15.
How any of the rescheduling might affect the New York Red Bulls' Kemar Lawrence and Derrick Etienne (Jamaica and Haiti call-ups for this window, respectively) it is difficult to say. It is unlikely to affect RBNY: the MLS playoffs are scheduled around FIFA's November international break. Both Lawrence and Etienne may have competitive soccer in November whether the Red Bulls advance deep into the post-season or not.
