BEREA, Ohio - Derek Anderson will replace Brady Quinn as the starting quarterback Sunday against the Bengals, coach Eric Mangini announced today.

Mangini said "giving Derek the opportunity is something I think will help us offensively.'' He said Anderson's performance on third down Sunday in Baltimore -- including 3-of-4 on a field goal drive -- helped him clinch the job. He said he needs to improve on throwing interceptions, after throwing three in Baltimore.

He also said he expects Quinn to continue to work hard. "I'm not saying it's all Brady,'' said Mangini. "Derek did some things that were positive and that's what it's based on.''

Details to follow soon.
