Holmes has been cleared by team doctors to practice and has passed his physical.
The Jets placed the wide receiver on the active-physically unable to perform list Tuesday, an expected move as Holmes recovers from a serious foot injury that ended his season last year after four games.
If Holmes is not ready to play when training camp opens, the Jets could place him on the physically unable to perform (PUP) list.
The eight-year veteran never said he disagreed with the move that will sideline him for at least six games. The 29-year-old lineman, however, made it clear on Monday that the Giants and their medical staff decided that his surgically repaired knee needed more time to heal.
New York Jets safety LaRon Landry has been activated from the physically unable to perform list after passing his physical, and has been cleared to practice when the team opens training camp on Friday.
The New York Giants have placed center Adam Koets on injured reserve and activated offensive lineman Kevin Boothe off the physically unable to perform list.
