DES MOINES, Iowa -- Iowa State linebacker Matt Robertson will not be allowed to play his senior season with the Cyclones after he tested positive for a banned nutritional supplement.

School officials said Monday that Robertson, who started all 12 games as a junior last season, must sit out one season under NCAA rules. His only option to play next season is to transfer to a non Division I-A program.

"I take full responsibility for taking an over-the-counter supplement that is banned by the NCAA," Robertson said in a statement released Monday. "I am paying a heavy price for a very bad decision, as I will never again wear an Iowa State uniform. I hope my example will serve as a warning to others contemplating use of dietary supplements."

Robertson tied for the team lead in tackles last season with 103. He tested positive for the banned substance last month.

"Ultimately, I have a deep feeling of sadness, because Matt Robertson has always been a team player, an academic all-Big 12 performer who was as good in the classroom as he was on the field," Iowa State football coach Dan McCarney said in a statement.

"Let there be no doubt, however, his decision was unacceptable."
