Rams head coach Mike Martz will undergo tests this week to find out what’s been ailing him. Doctors think he may be suffering from a condition called endocarditis, which is an infection of the hearts lining or heart valve. He’ll miss a couple days of practice, while tests are run

Last week Martz was shortly hospitalized because doctors believed he was suffering from a sinus infection. He coached in the Rams 44-24 loss to the Giants Sunday.
