PACKER NOTEBOOK: Adams, Burnett downgraded to doubtful
The downgrades for the two players came Saturday -- just like last week. Adams is still dealing with an ankle injury and Burnett has a calf injury.
The Packers also added cornerbacks Ladarius Gunter (heel) and Sam Shields (toe) to the injury report as probable.

Packers safety Sean Richardson has suffered a season-ending neck injury and the condition could end his NFL career.
Richardson has a herniated disk in his neck for the second time in his career, according to the Milwaukee Journal Sentinel. Richardson underwent a fusion surgery after suffering a similar injury in 2012 and missed the entire 2013 campaign.
The Packers added Richardson to their injury report on Thursday after he reported pain following Wednesday's practice. The severity of the injury became known on Friday.
The 25-year-old Richardson is in his fourth NFL season. He is one of Green Bay's best special teams' players.
--LB Clay Matthews (quadriceps) had his workload reduced from full the previous day to limited in the team's padded practice Thursday. The injury isn't considered to be serious, and Matthews should be fine to make his customary start Sunday against St. Louis.
--WR James Jones (hamstring) didn't do much in practice Thursday for the second straight day. Afterward, however, the veteran insisted he is fine and will be OK to play Sunday against the visiting Rams. "I'm a tough dude - sometimes," Jones said.
--RT Bryan Bulaga (knee) went through the team's practice in pads Thursday in limited fashion for the second straight day. Bulaga was involved in the individual drills before the rest of the indoor practice was closed to the media. Speaking before practice, head coach Mike McCarthy considered Bulaga's participation in what is typically the team's most extensive practice of the week to be an important step in his return to the field this week after having surgery for a torn meniscus in his left knee after Week 1. Bulaga is hopeful about playing and returning to the starting lineup Sunday, when the 4-0 Packers host the St. Louis Rams.
