Bears coach Lovie Smith said some of his offensive starters may up to the half.
"We're going to get into the first quarter and see how many plays we have," Smith said. "We could let some of the guys go a little bit longer than we normally do, maybe to the half or something like that.
"Different positions will do different things."
Smith declined to elaborate. But, given the shuffling along the offensive line, the Bears may want that unit to see some extended time together against the San Diego Chargers.
Smith also said Thursday was the team's first prep day for the Chargers.
"Challenging offense [and] defensively, we're going to play a lot of 3-4 teams this coming season, so it's good," Smith said. "It's a prefect preseason game to open up the season against."
With temperatures in the mid-90s, the Bears didn't don shoulder pads, and they ran a lot of drills at half- or three-quarter speed. Not a whole lot of highlights to mention, but here are a few.
* Safety Chris Harris had an interception for the third consecutive day. He got this one on a deflected ball.
* Craig Steltz got a lot of reps with the starting defense, opposite Harris.
* Veteran linebacker Hunter Hillenmeyer returned to practice. So did tight end Kellen Davis and young players Kahlil Bell and Greg Mathews.
* Nick Roach got most of the snaps Thursday with the starting defense.
