LOS ANGELES — C.J. Anderson rushed for 123 yards and two touchdowns, and Todd Gurley rushed for 115 more yards and another TD in the Los Angeles Rams’ first playoff victory in 14 years, 30-22 over the Dallas Cowboys in the divisional round on Saturday night. Gurley and Anderson punished the Cowboys’ normally sturdy run defense and sent the second-seeded Rams (14-3) to the NFC championship game for the first time in 17 years.
