The Green Bay Packers decided not to activate WR Koren Robinson for Monday nights game at Denver.
Robinson had been reinstated Oct. 17 after a year-long suspension for violating the NFL's substance-abuse policy.
Robinson practiced for the first time last Monday but had been sore all week as a result of his practicing.
The Packers have until 3pm today to promote Robinson and release a player from their roster to make room.
