LAKE FOREST, Ill. -- Chicago Bears safety Chris Conte (concussion), center Brian de la Puente (knee) and fullback Tony Fiammetta (hamstring) all practiced on a limited basis Wednesday as the team started to install its game plan for the regular-season opener this weekend against the Buffalo Bills.
The Bears ruled out No. 3 quarterback David Fales due to a shoulder injury he suffered last week in the preseason finale in Cleveland.
Conte is expected to receive medical clearance to face the Bills later in the week.
Safety Ryan Mundy practiced with a large bandage on his forehead after having 15 stitches removed Monday. Mundy sustained a deep laceration to his forehead in the third week of the preseason and for some time was unable to wear a helmet.
"My head is good enough for me to practice," Mundy said. "I got my stitches out Monday morning. Fifteen [stitches]. It's a minor setback, but I feel good out there, and I'm preparing to play on Sunday.
"I've just got to make sure [the wound] is covered up. I'm really trying to have as little contact as I possibly can right now to give it time to heal. But the doctors said it looks good."
Mundy said he switched to a Riddell brand of helmets in the wake of the injury.
