UPDATE, 11:17 p.m.: Coach Jon Gruden and executive vice president Bryan Glazer tell us there is plenty of optimism that Cash's injury isn't as serious as feared. Both say he had extensive movement in his extremities and Gruden confirms it was indeed a neck injury.

An actual diagnosis wasn't immediately available, as doctors will undoubtedly have to do further tests to get more information.
