Starting cornerback Kennard Banks, defensive end Cleyon Laing and linebacker Kevin Hamlin all have rejoined the team and are eligible to participate in all team activities, including Iowa State's Saturday night game against Army.
The players had been charged with illegal possession of a controlled substance after marijuana and marijuana seeds were found in the off-campus apartment they share in Ames, Iowa. All were arrested early Tuesday morning after warrants for their arrest were issued by the Central Iowa Drug Task Force.
Iowa State athletic department officials made the reinstatement decision after reviewing and discussing the circumstances of this situation with several senior school officials, including a representative of the student judicial system. After that, the decision to reinstate the players was made -- an action provided for in the department's discipline policy.
The players will be sanctioned under the parameters of Iowa State's athletic department drug testing policy. Additionally, the players may face sanctions from the student judicial system.
Banks was listed as Iowa State's starting left cornerback on the 2-1 Cyclones' most recent depth-chart roster. The senior from Boynton Beach, Fla., is tied for fourth on the team in tackles with 17, including one stop for a loss.
Laing, a redshirt freshman from Edmonton, Alberta, Canada, was listed as third-string at left end. Hamlin, a redshirt freshman from Jupiter, Fla., was not listed on the Cyclones' depth chart.
