The team is expected to have a timeline on his recovery after the procedure.
Pryor's first year in the nation's capital has been a slog, to say the least.
Not only has the 28-year-old been bothered by an ankle injury that held him out of Washington's Week 11 showdown with the New Orleans Saints, but he's failed to establish chemistry with quarterback Kirk Cousins.
After inking a one-year, $6 million deal, Pryor has mustered 20 receptions for 240 yards and one touchdown.
As those numbers indicate, Pryor hasn't been a particularly big component of the Redskins' scheme.
With Pryor sidelined, Jamison Crowder, Ryan Grant and Josh Doctson should function as Cousins' primary playmakers.
