HARRISON, N.J. – If Red Bulls training feels just a bit empty over the next two weeks or so, there is good reason why.

Five Red Bulls players and one Red Bull II player have been called into their respective national team camps during the September FIFA window.

Fidel Escobar, Michael Amir Murillo, Kemar Lawrence, Derrick Etienne Jr. and Cristian Casseres Jr. will depart for camps and international friendlies with their respective teams between Sept. 2-12.

NYRB II defender Allen Yanes also has received a call-up from Guatemala.

Fresh off their World Cup appearance, defenders Escobar and Murilllo will rejoin the Panamanian national team for its friendly against Venezuela Sept. 11. Escobar played and started all three World Cup Group G matches. Murillo started and played the first two matches, while missing the third due to yellow-card accumulation.

Lawrence will accompany the Jamaica for two international friendlies. Lawrence and the Reggae Boyz will face Ecuador Sept. 7 at Red Bull Arena and play the Cayman Islands two days later. He has made 46 international appearances, tallying three goals and four assists in 3,877 minutes.

Etienne, Jr. will return to the Haiti national team for the first time since its international friendly against Argentina May 30. Etienne, Jr. and Haiti will face St. Martin Sept. 10. The Red Bulls forward has tallied seven appearances for Haiti, recording one goal in 385 minutes.

Casseres, Jr., a midfielder, has received his first career call up for the Venezuela Under-20 national team. Casseres, Jr. will head down to Miami, Fla. to join the U-20 side for camp from Sept. 5-12. He has been a main fixture with Red Bull II, making 16 starts over 22 games while recording three goals and two assists in 1,481 minutes played.

Yanes, a left back, will join Guatemala’s senior team for camp and matches against Argentina Sept. 7 in Los Angeles and against Ecuador in Bridgeview, Ill. Sept. 11. The 21-year-old has made four appearances for NYRB II since joining the team in July from Antigua GFC.
