And with the injury to the United States' starting goalkeeper, Tim Howard, RSL's Nick Rimando appears in line for a call-up of his own. Last week, U.S. coach Jurgen Klinsmann told reporters Rimando would likely back up Aston Villa goalie Brad Guzan.
A loss, while not unexpected, would certainly be a blow to RSL.
"If you had to pinpoint a top performer for this first three matches, [Rimando's] name would certainly be at the top of the list of considerations," coach Jason Kreis said after Rimando's late heroics preserved a 1-1 draw against Colorado.
Salt Lake captain Kyle Beckerman has also seen regular duty in the Klinsmann era, leaving RSL with a hole to plug in its midfield.
Similarly, defender Abdoulie Mansally could receive a call-up from the Gambian team.
Mansally missed the match against Colorado after being suspended by Major League Soccer for a head-butt earlier in the season against D.C. United.
Real could see reinforcements from other places, though.
Midfielder Javier Morales has been training with the team, inching toward a return after a knee injury and surgery sidelined him early in the preseason. Defender Nat Borchers, who has been rehabbing after a quad injury, saw time on the field with RSL's reserves Saturday night in a 2-1 win over the Rapids.
And midfielder Ned Grabavoy, who missed the season's first two games due to a family matter, returned to action on Saturday as well, coming on as a second-half substitute for Khari Stephenson.
Kreis said it was "pretty clear to me that his fitness level is struggling a little bit" but added that he hoped to see Grabavoy available for all 90 minutes against Dallas.
