Larry McElreavy resigned as Columbia football coach, a week after one of his assistants accused him of professional misconduct.

McElreavy denied the charges and the university said it believed his denials, but McElreavy said he could not continue coaching.

Doug Jackson, Columbia’s offensive coordinator, had accused McElreavy of drinking before games, missing team meetings, and said McElreavy was “reeking of alcohol” during Columbia’s game against Dartmouth on Nov. 5.

Two doctors who treated the coach denied the allegations, saying that McElreavy had suffered a stress attack complicated by high blood pressure.
