Parker (concussion) won't play Sunday against the Colts, Evan Lazar of the Patriots' official site reports.
Though Parker was able to practice in a limited fashion Wednesday and Thursday, he was one of three players ruled out by the Patriots ahead of this weekend's game in Frankfurt, Germany. With Parker set to miss his second game in a row, the Patriots are expected to lean on Demario Douglas (ankle), JuJu Smith-Schuster and Jalen Reagor as their top three receivers. Parker will target a return to action Nov. 26 against the Giants following the Patriots' Week 11 bye.
