CINCINNATI (AP) -- Bengals receiver Andrew Hawkins will wear a cast for 10 days to try to heal his sprained left ankle, making it doubtful he'll be ready for the season opener.

Coach Marvin Lewis said on Saturday that Hawkins will be evaluated again in 10 days. If he's not ready for the opener Sept. 8 in Chicago, he could be placed on injured reserve with an opportunity to return at some point during the season.

Hawkins was Cincinnati's second-leading receiver last year with 51 catches for 533 yards and four touchdowns.

Also on Saturday, the Bengals signed guard Otis Hudson, a second-year player who was on their practice squad in 2010 and on the roster for seven games last season.
