Shoulder issue??

So apparently Mark Sanchez is having some shoulder pains. An MRI revealed no rotator cuff, tendon, or bone damage. It did, however, show that his cartilage is "torn". Cartilage is the cushioning between your bones that prevents them from rubbing together. It is more like a mesh than a tendon. So it can't exactly be torn, it can be poked or pitted. A source inside the Jets organization says that the injury will not get worse if 

he continues to play. It may be wise to rest Sanchez this week since the Bears have a devastating pass rush. The Jets cannot afford to have their franchise QB take a pounding with playoffs on the line. The team may end up getting in the playoffs whether they win or lose on Sunday. There is a good chance Jacksonville or Indianapolis will lose Sunday and get the Jets in. So should they rest Sanchez this Sunday and have him completely healthy for the Bills game? Or play him this week with the risk he could be tentative or be inaccurate?
