CINCINNATI – Bengals tight end Jermaine Gresham reportedly is sidelined by hernia surgery, prompting the team to re-sign Alex Smith, who became an unrestricted free agent after the 2013 season.
ESPN reported that Gresham had surgery during the offseason. Coach Marvin Lewis would only acknowledge that Gresham had a "physical issue."
Gresham has been present for mini-camp this week but has not worked out with the team.
Smith, a 10th-year NFL player, joined the Bengals as a free agent from the Browns last season and caught 13 passes for 47 yards. A wrist injury forced him to miss the playoff loss to the Chargers.
Lewis said that if training camp opened this week, cornerback Leon Hall would be lined up as a starter. Hall is ahead of schedule in recovering from his second torn Achilles' tendon in the past three years. He didn't participate in full-team drills on Tuesday.
Lewis was much more guarded about defensive tackle Geno Atkins, who is coming back from a torn ACL suffered on Oct. 31. It's unclear whether he'll be ready to start the season.
Defensive tackle Devon Still was not present. He was granted permission last week to attend to personal matters. He announced on social media that his young daughter has cancer.
