Chapman, a 5-11, 180-pound senior from San Francisco, Calif., had three interceptions in the Wildcats' 44-30 victory over Oklahoma State. His three interceptions tied for the second-most in school history and were the most by a Wildcat since Chris Canty had three against Akron in 1995.
He returned his first interception 29 yards for a touchdown in the second quarter. In addition to his interceptions, Chapman recorded five tackles and batted away two passes.
Chapman, the final FWAA national defensive player of the week selection for the season, will be added to the 2012 Bronko Nagurski Trophy Watch List. Five finalists for the Bronko Nagurski Trophy will be announced by the Football Writers Association of America on Nov. 15. The winner will be revealed on Dec. 3 during a banquet that the Charlotte Touchdown Club sponsors at the Westin Hotel in Charlotte, N.C.
Each Tuesday during the 2012 season the FWAA All-America Committee has selected a national defensive player of the week from nominations made by the 11 Division I Bowl Subdivision conferences and major independents.
The FWAA has sponsored a National Defensive Player of the Year award since 1993 and has named a National Defensive Player of the Week since the 2001 season.
