* Quarterbacks Kyle Boller and Troy Smith, linebacker Dan Cody, running back P.J. Daniels, fullback Jake Nordin and offensive tackle Mike Kracalik are sporting what coach John Harbaugh called “arm and hammer” patches on the left shoulders of their jerseys. The patches signify participation in at least 85 percent of the team’s offseason workouts.

* Jared Gaither is at training camp, but the projected starter at left offensive tackle did not practice.

* Because there are no cornerbacks at camp (rookie safeties Haruki Nakamura and Tom Zbikowski are the only defensive backs), defensive end Trevor Pryce and secondary coach Chuck Pagano lined up at cornerback during 7-on-7 drills.

* During a drill involving being attached to a goalpost via a gigantic rubber band, Daniels was snapped back and onto his rear end. Undeterred, Daniels popped back up and finished the drill.
