Penn State wrestling coach Troy Sunderland has resigned after the team dropped to seventh place in the Big Ten in spring of 2009. Athletic director Tim Curley said the resignation took effect immediately. The school will begin a national search for a replacement. Sunderland coached 11 seasons at his alma mater, with four top 10 finishes at the NCAAs, including a third-place finish in 2008. The Nittany Lions slipped to 17th at nationals this season.
