Wendell Tyler rushed for 138 yards and scored two touchdowns to lead the Los Angeles Rams to their first victory of the season, 20-14, over the Kansas City Chiefs today.

The Rams won only their second in 11 games dating to last season. Both teams are 1-3.

Tyler fumbled three times and the Chiefs recovered twice, the second time with four minutes to play at the Los Angeles 26. But Kansas City was unable to score what could have been the go-ahead touchdown.

Billy Jackson put the Chiefs ahead, 7-0, in the first quarter with a one-yard run. It ended a 69-yard drive that took 18 plays.

Tyler's touchdowns came in the second period on runs of one and 23 yards, completing drives of 62 and 75 yards.

The Rams drove to the Chiefs' five in the third quarter but Tyler, fumbled and Kansas City's Thomas Howard recovered.

A few minutes later, LeRoy Irvin returned a punt 63 yards to put Los Angeles ahead, 20-7. He fielded the ball on one hop, cut to the right and scored untouched. It was the first touchdown the Chiefs had yielded on a punt return since 1976.

"I wasn't trying to catch it because the guy was right on me," Irvin said. "It took a short bounce and I was backing up to stay away from it, but it popped right back in my hands.

"All week, us younger guys felt we let the veterans down. They worked long and hard to establish a winning tradition and now it's our job to step in and help them win again."
