Parker (concussion) has been ruled out for Sunday's game against the Commanders, Evan Lazar of the Patriots' official site reports.
Per Mike Reiss of ESPN.com, Parker was spotted at the media-access portion of Friday's practice, but he ended being listed as a non-participant and won't see Week 9 action. With Parker unavailable and Kendrick Bourne (knee) on IR, the Patriots' top current healthy WRs are Demario Douglas, JuJu Smith-Schuster and Jalen Reagor, with Tyquan Thornton (foot, questionable) -- if active -- and rookie Kayshon Boutte also candidates to get in the mix. Parker now will target a potential return to action Sunday, Nov. 12 against the Colts.
