On Monday, Paea said he would sign with Washington, according to Ian Rapoport of NFL Network.
Paea, who turns 27 in May, spent the last four seasons with the Chicago Bears. He started all 16 games last season and was third on the team with six sacks.
Greg A. Bedard of The MMQB ranked Paea as the 43rd-best available free agent and the sixth-best free agent defensive tackle.
Washington released defensive tackles Barry Cofield and Stephen Bowen earlier this offseason and also signed Ricky Jean-Francois.
Washington ranked 22nd in the league in sacks last season with 36. The team also risks losing pass rushing linebacker Brian Orakpo.
