Bears lose Blanchard with fractured knuckle

CHICAGO -- The Chicago Bears plan to add another quarterback to the roster in the coming days after losing third-stringer Matt Blanchard for an unspecified period when he fractured a knuckle on his left hand Thursday during the club's 33-28 preseason win over the San Diego Chargers.

Blanchard suffered the injury when he was sacked with 8:03 left in the third quarter for a 10-yard loss by Jarius Wynn.

"I'm not sure about the time that he'll be out, but we're sitting here with two quarterbacks going into next week," Bears coach Marc Trestman said. "Certainly that's something that we're gonna have to repair fairly quickly to get a third quarterback on the roster."

Former Oakland Raiders No. 1 overall pick Jamarcus Russell worked out for the Bears in June, and drew positive reviews from those in attendance, who raved about the quarterback's arm strength. The club also worked out Trent Edwards and Jordan Palmer the same day as it attempted to cull together up-to-date evaluations on those players so it could gather a short list of veterans it could call upon in the event of an injury.

"We've got to get another quarterback in here, and I'm sure we'll look to do that as we move forward," Trestman said.

An undrafted free agent in 2012, Blanchard, a native of Lake Zurich, Ill., spent 12 weeks last year on the practice squad. Blanchard had drawn praise from Trestman and offensive coordinator Aaron Kromer for his quick grasp of the offense, decision-making skills and his confidence.

Blanchard completed 16 of 19 in two preseason games for 193 yards and an interception. Against the Panthers in the exhibition opener at Carolina, Blanchard scrambled four times for 26 yards.
