Lewis told reporters at the NFL's Annual Meeting on Tuesday that he wouldn't "rule it out" that the club could offer the free-agent receiver another contract. Simpson has spent his four NFL seasons with the Bengals.
Simpson pleaded guilty on March 1 to a drug-related charge resulting from two pounds of marijuana shipped to his home in September. Prosecutors recommended a 60-day jail stay. A judge will decide whether to lessen the punishment at a hearing on April 5.
Simpson also faces a possible four-game suspension from the NFL.
