The U.S. returns to international play on Feb. 8 with a game against France in Lorient. The Americans follow that with a match against England on Feb. 13 in Milton Keynes.

Barnhart, who helps coach goalkeepers at Stanford, joined the team for the first time since September. She's one of four goalkeepers to be invited.

Press appeared in 23 of the Americans' 24 games in 2014 and is one of the team's top scorers. O'Hara, who switched to defender with the U.S. team, was used as a forward in a recent trip to Brazil. She replaced Press, who had a family emergency.

U.S. coach Jill Ellis announced the 29 players who were invited to camp Monday. The roster will be trimmed to 23 for the FIFA Women's World Cup that opens in June in Canada.

Stanford grads Christen Press, Kelley O'Hara, Nicole Barnhart and Rachel van Hollebeke (formerly Rachel Buehler) were all named to the United States women's national soccer team that will begin preparations for the World Cup with a three-week training camp beginning Monday at the national training center in Carson.

"After much thought and discussion with my family and coaches, I have decided to continue my education at Stanford," Morris said in a statement. "My teammates, coaches, professors and peers make Stanford a special place. Here, I am provided the unique opportunity to both play the game I love and learn at one of the world's great universities."

Morris, who was called up to play for the U.S. national men's team, is considered one of the top pro prospects in the nation.

Stanford won the Pac-12 title but was upset, in overtime, by UC Irvine in the second round of the NCAA tournament. It was the Cardinal's first conference title since 2001.

"Playing professionally is a dream of mine and I feel that Stanford will prepare me extremely well to realize that goal, but also for life after soccer," Morris said. "I am fortunate to have the opportunity to represent this university both on and off the field and look forward to working with my teammates to make our 2015 season a success."

Morris earned an earlier call up to the national team camp for its Sept. 3 friendly against the Czech Republic in Prague, making him the first current collegian to join the national team in 15 years. He also made two appearances with the U.S. U-23 Men's National Team at camps in Nassau, Bahamas (Aug. 3-7) and Brasilia, Brazil (Oct. 10-13).

We are very excited that Jordan is committed to his future here at Stanford," Cardinal coach Jeremy Gunn said. "He is an outstanding person and an exceptional soccer player. We are left with no doubt, that when the time is right, Jordan will move on to become a very successful professional athlete."

Morris became the first active collegian since 1995 to receive a cap for the U.S. Men's National Team when he came on in the 76th minute in a friendly against Ireland in Dublin.
