Rookie David Perron apparently will not be returning to juniors. The 26th overall pick in this past June's draft, Perron is expected to be in the Blues' lineup Saturday, when the club takes on the Predators at the Sommet Center. The contest will be the 19-year-old Perron's 10th with the Blues, meaning he will fulfill the first of seven years of service required for free agency under the National Hockey League's collective bargaining agreement.
