AMES, Iowa – Iowa State junior linebacker A.J. Klein was named Big 12 Defensive Player of the Week the league office announced today. A media panel selected Klein to his first weekly league honor.

Klein registered a season-high 14 tackles, forced a fumble and was credited with a quarterback hurry in Iowa State’s 37-31 double-overtime win over No. 2 Oklahoma State Friday night at Jack Trice Stadium.  The Kimberly, Wis., native helped the Cyclones produce their first-ever victory over a team ranked in the top six in the Associated Press Poll.

Klein additionally had a pass break up and a tackle for loss, as the Cyclones forced five turnovers and held the vaunted Cowboy offense to only 60 rushing yards.
