The goalkeeper's pending back surgery is set to leave United without any experienced shot stoppers for the foreseeable future.
D.C. United goalkeeper Andrew Dykstra will have back surgery on Friday and miss 10 to 12 weeks, the club has announced.
With normal starter Bill Hamid already sidelined until midseason after knee surgery, United is left with just two goalkeepers on its roster.
Travis Worra, an undrafted free agent DCU signed before last season, made his first MLS start against New England on Sunday and could be set for an extended run as the club's starter.
