It started with Bears linebacker T.J. Edwards picking off Brock Purdy on the first play of the game and returning it 34 yards for a touchdown. Unfortunately for Chicago, that was one of the few things the defense did right in the first half.

Purdy followed up his career-high five TD-pass performance last week against Indianapolis by throwing for three scores and running for two.

Battling for the potential No. 1 seed in the NFC, Brock Purdy and the San Francisco 49ers defeated the Chicago Bears 42-38 at home Sunday.

San Francisco 49ers left tackle Trent Williams suffered a right hamstring injury in the first quarter Sunday against the Chicago Bears, and was replaced on the line by Austen Pleasants, who had played just 12 offensive snaps this season before the game.

Brock Purdy threw a 38-yard touchdown pass to Jauan Jennings with 2:15 to play, and the San Francisco 49ers forced an incomplete pass on the final play from the 2 to beat the Chicago Bears 42-38 and set up a Week 18 showdown for the top seed in the NFC.
