Walker performs limited duties

EVANSTON, Ill. -- Northwestern football coach Randy Walker
was back at practice Wednesday after spending two days in the
hospital because of an inflammation of the heart muscle.

Walker, released from Evanston Northwestern Hospital early
Wednesday afternoon, arrived on campus a short time later. He held
a team meeting and performed limited duties at practice, spokesman
Mike Wolf said.

Walker, 50, checked himself into the hospital on Monday after
experiencing chest pains before his weekly news conference. Tests
showed that his heart is fine, but they also revealed the
inflammation, known as myocarditis.

Doctors are still trying to determine what caused the disease,
Wolf said. Myocarditis is not a common ailment, and it's usually
caused by a virus.

Northwestern (3-4, 2-2 Big Ten) hosts Purdue (No. 19 ESPN/USA Today, No. 17 AP) on Saturday,
and Walker's doctors think he will be well enough to be at the game.

"If he continues to progress ... we expect he will be there
Saturday, most likely on the sidelines," Wolf said.
