ESPN is stating that the Jets may put Mark Sanchez on injured reserve instead of cutting him if they decide to replace him. He has a large guaranteed contract and cutting him is a large salary cap hit.
Sanchez clearly does not have a season ending injury. My understanding is that the player has to clear waivers before he can be put on injured reserve, but that isn't a lot of protection, no team has cap space left at the start of the season.
So can a team arbitrarily decide to put you on injured reserve no matter what?
