Chicago Bears linebacker Brian Urlacher called the minor left calf strain that knocked him out of Saturday's exhibition loss the Raiders "no big deal.''
Urlacher suffered the injury on the game's first drive.
"On like the third play, I was running and I felt like a cramp,'' he said. "Then on the next play, I couldn't put pressure on it. Then I was out.
"I had a similar-type injury (in 2007) on a Tuesday, and I ended up playing that Thursday (at Washington). I'm not going to speculate on how long, but I'll be fine.''
Urlacher enjoyed an injury-free training camp after making a full recovery from wrist surgery that ended his '09 season after just one game. He was held out of the first training camp practice in pads only because it was prescheduled by the doctors.
