Washington has signed Terrelle Pryor Sr. to a one-year, $8 million deal.
Washington lost DeSean Jackson and Pierre Garcon at wide receiver this offseason.
Pryor led the Browns with 77 receptions, 1,007 yards and four touchdowns last season.
Pryor became the second player in NFL history to have seasons with 1,000 passing yards and 1,000 receiving yards. The last was Marlin Briscoe, who had 1,589 yards passing in 1968 and 1,036 receiving in 1970.
