Purdue defensive end Ryan Kerrigan has been named the FWAA/Bronko Nagurski National Defensive Player of the Week for games of the weekend of Oct. 17. Kerrigan, a 6-4, 263-pound junior from Muncie, Ind., had a team-high nine tackles, four tackles for loss, three sacks, two forced fumbles and a fumble recovery in Purdue's 26-18 upset of No. 7 Ohio State. On the third play of the game, Kerrigan took the ball from the Buckeyes' quarterback. In the second quarter, he posted a 21-yard sack, knocking the ball free again and recovering it. Kerrigan's tackles for loss resulted in minus-37 yards for the Ohio State offense. Kerrigan will be added to the 2009 Bronko Nagurski Trophy Watch List. The Bronko Nagurski Trophy will be presented to the best defensive player in college football on Dec. 7 by the FWAA and the Charlotte Touchdown Club at the Westin Hotel in Charlotte, N.C. Five finalists for the Nagurski Trophy will be announced on Nov. 18 or 19.
