DAVIE, Fla. — Miami Dolphins cornerback Will Allen is out for the season with a left knee injury.

Allen hurt his anterior cruciate ligament in the third quarter of the Dolphins' loss to New Orleans and will require surgery, coach Tony Sparano said Monday.

Allen has missed only one game since joining the Dolphins in 2006. He leads the team with two interceptions this year.

He'll be replaced by 2009 first-round draft pick Vontae Davis, which means the Dolphins will start two rookie cornerbacks Sunday at the New York Jets. Second-round pick Sean Smith has been starting opposite Allen.
