CINCINNATI (AP) Linebacker Vontaze Burfict moved smoothly during an individual workout on Monday but didn't practice with the rest of the Cincinnati Bengals when they returned from their bye.

Burfict is eligible to return to practice this week. He opened the season on an injury list as he recovered from offseason knee surgery. Coach Marvin Lewis declined to reveal the plan for Burfict this week.

The Bengals (6-0) will be trying for the best start in their history when they play Sunday at second-place Pittsburgh (4-3). Cincinnati can take control of the AFC North with a win.

The Bengals have avoided significant injuries during their perfect start. Burfict is the only starter who has missed significant time.
