UPDATE: Oniel Fisher has also been added to Jamaica's preliminary roster. They play Chile on May 27 in a Copa America warmup match.
Turns out Copa America Centenario will affect the Seattle Sounders a bit more than originally thought. Although MLS will take a break during the group stage, the United States is playing a trio of friendlies beforehand. MLS players are expected to be excused from the first one against Puerto Rico on May 22, but will be expected to participate in matches against Ecuador (May 25) and Bolivia (May 28).
Clint Dempsey, Brad Evans and Jordan Morris have been named to the USMNT's preliminary 40-man roster, which is supposed to be trimmed to 23 on May 20. Roman Torres has also been named to Panama's preliminary roster and Nelson Haedo Valdez is on Paraguay's roster. Panama plays Brazil on May 29 while Paraguay plays Mexico on May 28.
In a worst-case scenario, the Sounders could be without all five players for road matches against the New England Revolution (May 28) and D.C. United (June 1). If the United States, Panama or Paraguay advance beyond the group stage, the Sounders could also be without some of them for the road match against the New York Red Bulls on June 19.
"It's just the way it is," Sounders head coach Sigi Schmid told reporters on Monday. "It's something we knew was going to happen, we weren't going to be able to stay completely clear of that."
