EVANSTON, Ill. -- Northwestern football coach Randy Walker checked himself into the hospital Monday after becoming ill before a news conference.
School spokesman Mike Wolf could not comment on Walker's illness but said Northwestern expected to release more information Tuesday.
Walker, 50, was to be kept overnight at Evanston Northwestern Hospital, the university said.
"I saw him tonight (at the hospital) and he was resting comfortably," Wolf said. "He was in good condition in his room watching Monday Night Football."
Walker took over as the Wildcats' head coach in January 1999, replacing Gary Barnett.
Northwestern (3-4) hosts Purdue on Saturday.
