LOS ANGELES — C.J. Anderson rushed for 123 yards and two touchdowns, and Todd Gurley rushed for 115 more 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.     

Ezekiel Elliott rushed for a TD and Amari Cooper caught an early TD pass for the Cowboys (11-7), who still haven't won a playoff game on the road in 26 years. After winning the NFC East and beating Seattle last week, Dallas lost in the divisional playoff round for the sixth consecutive time.

In the AFC in Kansas City quarterback Patrick Mahomes picked apart the Colts in his postseason debut, the Chiefs defense answered their chorus of critics with a stout performance, and Kansas City rolled to a 31-13 victory over Indianapolis in the divisional round Saturday to end 25 years of playoff frustration.     

Mahomes threw for 278 yards while running for a touchdown, and Damien Williams ran for 129 yards and another score, as the Chiefs beat Indianapolis for the first time in five playoff meetings to earn their first AFC title game appearance since January 1994.     

The AFC West champions will play the winner of Sunday's game between the division-rival Los Angeles Chargers and the New England Patriots next weekend for a spot in the Super Bowl in Atlanta.     

Andrew Luck was held to 203 yards passing for the Colts, while Marlon Mack was a non-factor on the ground. He had 46 yards rushing before leaving late in the fourth quarter with a hip injury.
