LAKE FOREST, Ill. — Bears star linebacker Brian Urlacher went on injured reserve after having surgery yesterday to repair a dislocated right wrist and will not be back this season, a major blow for a team with high expectations.

There was no immediate word from Urlacher other than a text message to the Chicago Tribune that said simply: “season is over.” But coach Lovie Smith said Urlacher clearly was disappointed.

“He had put himself in position to have an outstanding year,” Smith said. “It’s a tough break.”

The injury to Urlacher occurred in the first quarter of Sunday night’s 21-15 loss at Green Bay. Urlacher played in the second quarter, but left on the Packers’ first drive of the second half.
