LAS VEGAS -- - Josh Blackwell blocked a 54-year-old field-goal attempt by Daniel Carlson in the final minute to preserve a fourth-quarter rally led by Caleb Williams , and the Chicago Bears stunned the Las Vegas Raiders 25-24 on Sunday.

After D'Andre Swift 's 2-yard touchdown run with 1:34 left put the Bears (2-2) in front, Geno Smith led the Raiders (1-3) into position for Carlson's kick with 38 seconds left. Blackwell came in nearly untouched from the left side, dived and deflected the ball. He raced down the field in celebration as teammates chased him.

The Bears became the second team to win 800 regular-season games, joining the Green Bay Packers , who had 812 going into Sunday night's game at Dallas. The Raiders have lost three straight.
