HARRISON, N.J. – Red Bulls defenders Aaron Long and Kyle Duncan Monday were called into U.S. men’s national team for an international friendly against El Salvador in Fort Lauderdale, Fla. Dec. 9.

Long, a USMNT veteran, and Duncan, a newcomer, will head to Fort Lauderdale Monday.

Long heads back for international duty for the first time since captaining the USMNT in a 2-0 win over Costa Rica Feb. 1 at Dignity Healthy Sports Park. The Oak Hills, Calif. native missed out on the last two international friendlies as the USMNT roster was exclusively made up of players playing professionally outside the United States because the MLS season still underway and upcoming playoffs.

He has 17 internatonal matches including wearing the captain’s armband three times. He has recorded three goals and one assist in 1,432 minutes. He has helped anchor the USMNT to eight clean sheets and a 10-5-2 record when he starts.

Duncan earned his first senior team call-up after multiple call-ups at the youth national team level, including appearances with the Under-18 squad. The New York City native has logged two appearances for his country with the U-18 team against the Germany in December 2014.

The outside back enjoyed a career year as he tallied season highs in goals (three), assists (four), games played (23), games started (21) and minutes played (1,908). He registered his first career multi-point performance with one goal and two assists in the season opener against FC Cincinnati March 1 and followed up with the game-winning goal against New York City FC Aug. 20.
