Caleb Porter has called in three more players to the ongoing U-23 US national team camp in Carson, Calif.
Goalkeepers Matt Lampson (Columbus Crew) and Brian Perk (LA Galaxy) will join the team at The Home Depot Center, while Stuttgarter Kickers defender Royal-Dominique Fennell has also been added to the squad.
Additionally, goalkeeper David Bingham and defender Gale Agbossoumonde, both of whom were part of the original 22-man squad, will not attend due to injury.
Lampson and Perk were each called up for the first time by Porter. Fennell has participated in both of the previous two U-23 camps in Germany and Florida.
The current gathering consists of 11 days of training at the HDC unti Jan. 18 before the U-23s travel to Costa Rica to play against two local club teams. The camp marks the third gathering of this group, as the team prepares for the March 22-26 Olympic qualifiers against Canada, El Salvador and Cuba at LP Field in Nashville, Tenn.
