Todd Bowles was admitted to a hospital Friday afternoon with an undisclosed illness and didn't travel with the Jets for their road game Saturday against the Patriots.

Bowles began throwing up, experiencing chest pains, back pains, and after he was given medication, he could not keep it down, which is when Jets officials became extremely concerned and took him to the hospital. 

The fear was Bowles was suffering a heart attack but doctors ruled that out.

If Bowles cannot coach on Saturday, Mike Caldwell will assume duties on an interim basis.
