Peyton Manning was a full participant, while Wes Welker, Julius Thomas, and Joel Dreessen made limited returns; Champ Bailey was again limited.
None of the four moved on to the final round last year.
In all, 19 players and six coaches/execs made the initial cutdown, and 15 of those 25 will join senior nominees Ray Guy and Claude Humphrey as finalists on January 8.
Peyton Manning (ankle), Wes Welker (concussion), Julius Thomas, (knee), and Joel Dreessen (knee) were held out of practice on Wednesday.
Champ Bailey (foot) was limited, while six others were listed on the injury report as full participants.
Manning is expected to practice on Thursday and Friday in preparation for his 14th showdown with Tom Brady.
Peyton Manning and the Broncos may face a decimated Patriots secondary on Sunday night in Foxboro. New England is expected to be without CB Alfonzo Dennard, who missed Monday's loss to Carolina due to an injury that reportedly required his knee to be scoped.
Corner Aqib Talib, who allowed Steve Smith to occupy his dome for much of Monday night, was sidelined late in the game after aggravating a hip injury that had caused him to miss the Pats' three prior games.
There's apparently much more to the Rahim Moore story that we haven't heard. Here's what Vic Lombardi had to say earlier today (11/19 hour 2) on 104.3:
Listen to what I'm saying here. Listen to these words--there is more to this story. There is more to this story, and depending on how quickly it gets out there, it could get ugly, cause Rahim Moore was feeling pressure and pain in that lower leg area all week. It didn't happen in game time. It didn't just occur. He didn't show up Sunday night, dancing around, feeling healthy, and suddenly the leg gets banged. He was feeling that all week. Some people knew about it...
Moore played 30 snaps during Denver's 27-17 win over Kansas City on Sunday night before leaving with what was characterized on NBC as a mysterious leg injury.
He was replaced by Mike Adams, never to return, and underwent surgery Monday morning.
According to the Denver Post, free safety Rahim Moore will miss "several weeks" with what is being called a "serious lower leg injury."
Moore had two tackles and defensed one pass prior to his second quarter departure on Sunday night.
According to Mike Klis, Jack Del Rio interviewed for the vacant USC head coaching job during Denver's bye week.
JDR's met with his alma mater on Friday, November 1, a day before the health scare that sidelined John Fox and made Del Rio the Broncos' interim coach.
Peyton Manning, Duke Ihenacho, and 11 other Broncos are listed as probable for Sunday night's showdown with the visiting first-place Chiefs.
But as Jack Del Rio put it Friday, he'd list his quarterback's status as "definite," if that were possible on NFL injury reports.
Denver's full roster practiced, but Champ Bailey continued to work with the scout team, and is listed as doubtful.
Peyton Manning, Joel Dreessen, and Nate Irving returned to practice Thursday, albeit in a limited fashion. Champ Bailey and Duke Ihenacho practiced again, but were again limited.
Manning had been sidelined Wednesday to rest his ailing right ankle, which was heavily taped during practice. He also wore a glove on his throwing hand, perhaps in anticipation of cold conditions at SAF@MH on Sunday night.
