Kansas (KU) football's game against Texas Tech sparked controversy due to objects being thrown onto the field.
According to KU head coach Lance Leipold, a pocket knife was thrown onto the field in the third quarter, hitting a KU staff member.
Texas Tech has a tradition of throwing tortillas on the field during kickoffs at home football games.
The Big 12 announced a rule change before the season, stating that the first two incidents of fans throwing objects on the field would result in warnings, and subsequent incidents would incur a 15-yard penalty.
A pocket knife was thrown and hit one of our staff members, said Leipold.
