Chris Harris leaves camp practice

BOURBONNAIS, Ill. -- The Bears were forced to slightly alter their secondary Saturday morning after veteran safety Chris Harris left the morning walk-through for undisclosed reasons.

Craig Steltz took the starter's reps in place of Harris, while rookie Major Wright and veteran Josh Bullocks spent the practice working with the second team.

Although Steltz is held in high regard by the organization, many expect Wright, a 2010 third-round draft choice, to one day crack the starting lineup. Wright put together an impressive offseason, but all those workouts were conducted without pads. Known as a big hitter at Florida, the rookie safety is eager to get his first taste of NFL-level full contact on Saturday night.

"Being in pads, you can tell who's physical or who's just laid back and really not a physical type," Wright said. "The pads show a lot. That's all a part of being a football player. I was pretty physical [in college], but that's just one part of the game. This game has many parts, and you have to play all those parts.

"I'm learning, picking things up on both defense and special teams. Those veterans definitely help me out. If I do something wrong, they correct me and show me the right way to do things."

Bears head coach Lovie Smith does not address the media in the mornings, but is expected to give an injury update after the evening session.

Tight end Brandon Manumaleuna and cornerback Tim Jennings both sat out the morning practice.
