Jackson interviews for Duke post

Washington Redskins: Redskins offensive coordinator Hue Jackson, who has an extensive college background, interviewed Tuesday for the head coach job at Duke University, school and league sources confirmed for ESPN.com.

The school fired Carl Franks in mid-October and defensive coordinator Ted Roof has served as interim head coach since that time. Roof is a candidate for the job, as well, and the team has demonstrated improvement on his watch.

Another current NFL offensive coordinator, Marc Trestman of the Oakland Raiders, is said to be interested in the Duke vacancy. It is not known if Trestman has interviewed with Duke officials. Neither is it known what kind of timetable Duke is operating under or when they will make an offer to a candidate.

Jackson, 38, is in just his third NFL season. He joined the Redskins staff in 2001, under then-coach Marty Schottenheimer, was retained by Steve Spurrier, and then elevated to the coordinator spot late last season. Jackson has called the plays in some games this year, although Spurrier reclaimed that responsibility last week.

In 14 seasons at the college level, Jackson has served on staffs at Pacific (1987-89), Cal State-Fullerton (1990), Arizona State (1992-95), the University of California (1996) and Southern California (1997-2000).

Cincinnati Bengals: Veteran free agent linebacker Frank Chamberlain, who went from challenging for the starting middle linebacker job with the Titans this summer to being released altogether, has signed a two-year contract with the Bengals.

The move provides the Bengals another experienced defender at a key position as the team heads into the playoff stretch run still in contention for the AFC North title. And by signing Chamberlain to a deal beyond just the remainder of this season, it gives coach Marvin Lewis a player who could compete for a starting role in camp next summer.

A four-year veteran, Chamberlain, 25, played in 43 games and started three during his time with the Titans, posting 44 tackles and one sack. To create a roster spot for him, the Bengals released defensive end LaDairis Jackson.

New Orleans Saints: With backup Ki-Jana Carter ruled out for the balance of the season because of a foot injury, the Saints have signed free agent Lamar Smith to serve as their No. 2 back behind Deuce McAllister.

Smith, 32, previously played with the Saints in 1998 and 1999.

The nine-year veteran, who has been a starter with three different teams at junctures of his career, was released by Green Bay this summer. He spent the 2002 campaign with the Carolina Panthers, and led the team in rushing, but was suspended after a DUI incident.

It is unlikely that Smith will be active for Sunday's game against Washington, since he must still assimilate the playbook, and little-used James Fenderson will probably be the No. 2 tailback. Carter is expected to have surgery this week to repair ligament damage to a toe on his left foot. He has been placed on injured reserve.
