Powerhouse Trinidad and Tobago took a pounding in the latest FIFA world rankings released last week, as St Kitts and Nevis and Haiti also lost significant ground.
The Reggae Boyz remain the highest-ranked CFU nation at 48th in the FIFA tables.
T&T, the only English-speaking Caribbean side to reach the final round of qualifying for the upcoming FIFA World Cup in Russia, fell 13 places to slip to 92nd in the world.
They also surrendered second place in the Caribbean Football Union rankings, slipping to third place as Curacao gained 11 places to replace them.
T&T's fall comes on the heels of two ordinary results in international friendlies last month when they edged GuadeloupeÂ 1-0 in Basse-Terre and drew nil-all with Martinique in Fort-de-France.
Today they take on World Cup-bound Panama in Port of Spain in another friendly.
Curacao, with their rise, meanwhile, have moved up to 71st in the FIFA world rankings, but French Caribbean side Haiti were not as fortunate, crashing out of the top-100 to be 108th in the world.
There were also slides for St Kitts and Nevis, who fell 19 places, with Grenada tumbling 12 spots and Dominica, 10.
Antigua and Barbuda enjoyed the best movement among CFU teams, climbing 15 spots to 124th in the world and fifth in the region. Last month, they beat Bermuda 3-2 in St John's before scoring late to draw 1-1 with Jamaica in Kingston.
