The U.S. women’s national team returns to training on Wednesday with 28 players in camp Feb. 14-21 at The Home Depot Center in Carson, Calif., to prepare for next month’s Algarve Cup. Following the camp, U.S. head coach Greg Ryan will name 20 players who will travel to the tournament to be played from March 7-14 in southern Portugal.

Shannon Boxx, a 2004 Olympic gold medalist, is the most notable returnee to the U.S. roster, having been cleared for full participation after not having played for the USA since May 9, 2006, against Japan. She will see her first full action in training since major knee surgery last July.

Four other regulars who did not travel to China in January for the Four Nations Tournament return to the U.S. team for training camp: forwards Kristine Lilly and Abby Wambach, midfielder Aly Wagner and defender Christie Rampone. Also back in camp are goalkeeper Jenni Branam, who spent some time recovering from a back injury and illness, and veteran forward Danielle Fotopoulos, who is a little more than a year removed from ACL surgery.

All the players on the Four Nations Tournament-winning team will be in camp with the exception of defenders Kate Markgraf and Stephanie Lopez. Lopez has school commitments at Portland, while Markgraf, who captained the team in China, will not attend this training camp to rest and recuperate some minor injuries. She could be available for selection to the Algarve Cup roster.

The USA will open at the Algarve Cup on March 7 against China, which it beat, 2-0, last month to win the Four Nations Tournament. The Americans will also face Finland on March 9 and finish first-round play against Sweden on March 12.
