Photos: Highlights of San Francisco 49ers 38-13 blowout against Chicago Bears

A 38-13 victory over the woeful Chicago Bears ended the 49ers’ three-game losing streak, but now an extended win streak must follow for a legitimate playoff push.

The 49ers (6-7) merely avoided losing ground in the congested NFC West race. They stayed two games behind first-place Seattle (8-5) and earned a shot Thursday night to pull even in second place with a win over the visiting Los Angeles Rams (7-6). The Cardinals (6-7) lost at home to the Seahawks while the Rams were en route to a home win against the Buffalo Bills.

Brock Purdy rebounded exceptionally from his 94-yard outing in the Buffalo snow. He passed for 325 yards and completed 20-of-25 passes with two touchdowns and no turnovers, including 258 yards in the first half as the 49ers built a 24-0 lead.

Purdy’s open-field muse was George Kittle, who racked up 151 yards on six catches, after his only catch last week came on the 49ers’ opening snap in Buffalo.

Jauan Jennings caught both of Purdy’s touchdown passes, and rookie Isaac Guerendo ran for two touchdowns in his staring debut in place of injured rushers Christian McCaffrey and Jordan Mason.
