Bengals' Clements doubtful for Sunday

The Cincinnati Bengals could be without both starting cornerbacks for Sunday's game against Jacksonville, as Nate Clements is considered doubtful because of a calf injury and Leon Hall is questionable with a hamstring issue.

Both players have missed practiced all week.

In addition, backup cornerback Jason Allen is doubtful because of a thigh problem. He missed the last two days of practice.

Also listed as questionable for the Bengals are center Jeff Faine (hamstring) and backup running back Bernard Scott (ankle). Both were limited in practice Friday.
