Four members of Bill O'Brien's coaching staff at Penn State -- defensive coordinator John Butler, wide receivers coach Stan Hixon, running backs coach Charles London and safeties coach Anthony Midget -- have submitted their resignations, effective Monday, a Penn State spokesman said.
Multiple reports say the four will join O'Brien's staff with the Houston Texans. O'Brien was introduced last Friday as the Texans' new head coach.
Strength and conditioning coach Craig Fitzgerald and two of his assistants, Dwight Galt IV and Sean Hayes, also have resigned from Penn State and are expected to work for the Texans. Special assistant Jim Bernhardt, special assistant to the head coach and a long-time friend of O'Brien's, also is heading to Houston.
Both Butler and Fitzgerald are graduates of La Salle College High School.
