National Football League owners meeting in Dallas yesterday selected Stanford Stadium in California as the site for Super Bowl XIX in 1985 and the Louisiana Superdome in New Orleans for Super Bowl XX.

There was speculation that Houston's Rice Stadium would be named as the site for the 1987 game, but the owners did not make that selection.

The 1983 Super Bowl will be played Jan. 30 at the Rose Bowl in Pasadena, Calif., with 1984's Super Bowl XVII set for Tampa Stadium in Florida.

It was also announced that this year's NFC title game will be played Saturday, Jan. 22, at either 1 or 5 p.m. (EST), depending on the site, and the AFC championship game at either 1 or 5 p.m. the following day.

The NFL's competition committee discussed Sunday's controversial snow-clearing incident in New England, said Tex Schramm, president of the Dallas Cowboys and chairman of the committee.

Patriots Coach Ron Meyer ordered the driver of a snowplow onto the field with less than five minutes left in the game to clear the area before place-kicker John Smith made the 33-yard field goal that beat Miami, 3-0.

As a result of that incident, Schramm said, game officials will be instructed in the future to meet with both coaches prior to games played in ice and snow to discuss ground rules for use of equipment.

Asked if he anticipates that Commissioner Pete Rozelle will take punitive action against Meyer or the Patriots, Schramm replied: "I wouldn't be surprised."

Dolphins Coach Don Schula protested the snowplow incident, but referee Bob Frederic said game officials had no control over driver Mark Henderson, who had spent most of the day clearing yard-line stripes.

Schramm disagreed. The referee could have moved the ball to the other hashmark, where Smith would have been forced to kick out of the snow, Schramm said. Or Frederic could have penalized the Patriots if he had been made aware that Meyer ordered the sweep.

In Los Angeles, there were reports that Rams Coach Ray Malavasi will be out of a job at the end of the year following 11 losses in the team's last 13 games.

A story in the Los Angeles Times said Denver Broncos Coach Dan Reeves in in line for the job and one in the Riverside Press-Enterprise said it's Philadelphia Eagles (and former UCLA) Coach Dick Vermeil. An article in the Los Angeles Herald Examiner said Rams owner Georgia Frontiere hasn't made up her mind.

Malavasi told reporters at a breakfast meeting in Anaheim: "There's a lot of speculation going on in the newspapers. I would like you to know I am under contract with the L.A. Rams until Feb. 1, 1984. I am here to coach football. That's what I plan to do."

The Times story also said there will be a new general manager, University of Hawaii Athletic Director Ray Nagel, who would replace Jack Faulkner, and a new director of player personnel replacing John Math. It also said consultant Don Klosterman would not be retained.

In Houston Monday night, Dallas Cowboys safety Michael Downs had only one worry about accepting an early Christmas gift from Houston Oilers rookie Gary Allen -- he feared he might get caught from behind.

Downs scooped up Allen's fourth-quarter fumble and ran 86 yards for a touchdown in the Cowboys' 37-7 victory that clinched a National Football League-record 17th straight winning season.

The victory gave the Cowboys a 5-1 record, putting them in a tie with Washington for first place in the National Football League's National Conference standings. Houston is 1-5 in the AFC.

"I kind of thought about getting caught," Downs said after his gamebreaker. "It's kind of embarrassing for them to run you down from behind. They were inside the 10-yard line and just for us to have possession of the ball was a plus for us."

The Cowboys already were in control of the game, leading, 20-7, but Downs' play came when the Oilers were at the Dallas seven and put the visitors in command.

"It bounced perfectly for me," Downs said. "And I was just able to pick it up and run with it.

"I've never scored a touchdown in all my years of playing football, so for me to score a touchdown now is probably the best thing that could have happened to me. I've been a defensive player for as long as I've been playing."

Dallas quarterbak Danny White threw three touchdown passes, two to Butch Johnson, and failed on only six passes all night, completing 21 of 27 for 279 yards.

"I think we're in midseason form," White said. "I don't think there's any question about that..."
