Cornerback David Jones (Achilles' tendon), wide receiver Pierre Garçon (foot) and safety Brandon Meriweather (knee) did not practice Thursday, Coach Mike Shanahan said.
Limited in practice were: fullback Darrel Young (hamstring), punter Sav Rocca (right knee), cornerback Cedric Griffin (hamstring), DeAngelo Hall (knee), Jordan Pugh (concussion) and defensive end Doug Worthington (calf).
Young and Rocca were not on the list Wednesday.
Nose Tackle Barry Cofield (shoulder) and tight end Fred Davis (knee) participated in full. Cofield was limited on Wednesday.
Shanahan all but ruled out Garçon for Sunday's game in New York. Meriweather, meantime, has been ruled out.
