The U.S. travels to Costa Rica for the first match on Sept. 6 and returns to the States to face Mexico in Columbus, Ohio on Sept. 10.
Rimando will likely be the third goalkeeper behind Tim Howard and Brad Guzan, while Beckerman is in the mix to play in the midfield alongside Michael Bradley.
After RSL's game against Portland on August 30, the team has a break until September 13, where they will take on Seattle. Due to the layoff, it would be surprising if the pair missed a RSL match.
