STATE COLLEGE, Pa. (AP) -- Penn State coach Joe Paterno is in a hospital undergoing tests and is being treated for apparent dehydration.

A team spokesman says the 81-year-old football coach was taken to Mount Nittany Medical Center by ambulance Thursday morning after feeling nauseated.

Guido D'Elia says Paterno has not been admitted to the hospital, but is currently undergoing tests.

D'Elia says Paterno still plans to make a trip Friday to Texas for a dinner with University of Texas football coach Mack Brown.

Paterno had been on a busy schedule of late, traveling to Philadelphia last weekend. He also recently returned from a meeting with Big Ten Conference coaches.
