AMES, Iowa (AP) Iowa State linebacker Levi Peters won't play his senior season because of a number of foot and knee injuries.
Peters, who started his career as a walk-on, made nine starts last season and ranked fifth in the Big 12 with three forced fumbles.
Peters had a pair of surgeries on his left knee before enrolling at Iowa State. Peters also had his left foot surgically repaired twice while with the Cyclones, and those combined with a torn Achilles tendon in his right foot have been too painful to recover from.
Peters, a captain, told the team about his decision to retire Monday.
Peters is the second Iowa State linebacker to walk away this winter. Luke Knott left the team in February, also citing numerous injuries.
