This morning's Rumour du Jour: CBS Entertainment will switch the News division's new one-hour magazine, "48 Hours," from 8 p.m. Tuesday to the 8 p.m. Thursday time slot currently occupied by "Tour of Duty" ...

"Tour of Duty," in turn, would march to the 9 p.m. Saturday slot currently occupied by "Houston Knights," presumably because "Tour's" audience would be a better lead-in to CBS News' "West 57th" at 10 ...

The changes, which are due to occur in mid-March, will be announced to CBS affiliates this weekend ...

Nobody was saying yesterday, but apparently "Houston Knights" may be heading for R&R at best and perhaps for an end of their tour of duty on the network, since they apparently haven't been selected to return to their original Tuesday time slot, which "48 Hours" has been occupying lately ...

In its first two outings at 8 p.m. Tuesday through last week, "48 Hours" averaged an 11.5/17 up against NBC's strong "Matlock," which has a lock on older audiences in that time period. Putting the best face on it, a source at CBS News suggested yesterday that more adults will be available on Thursdays for "48 Hours" as the kiddies flock to NBC's powerful duo of "The Cosby Show" and "A Different World" ...

In 14 appearances through last week, "Tour" had averaged a 10.9/17 on Thursday against "The Cosby Show" and "A Different World" ...

"Houston Knights," occupying a couple of different time slots, had averaged a 9.4/15 in 14 appearances ...

Besides that huge crowd on Pennsylvania Avenue Wednesday to greet the triumphant Redskins in person, there was a pretty good audience watching the proceedings on local television ...

According to Nielsen, Channel 7's coverage from 11 a.m. until 12:45 p.m. led the parade, as it were, with an 8.1 rating and a 26 percent audience share. Channel 9 was next at 7.6/25, from 11 to 1, followed by Four at 7.1/23 from 11 to 1, and Five at 4.6/16 from 11 to 12:45 ...

If each rating point represents 16,116 TV homes, that means that in addition to the 600,000 or so actually standing curbside Wednesday, 440,000 homes were tuned to the Redskins, to say nothing of a whopping 90 percent of the sets in use ...

Arbitron figures gave Seven a 7.6/26, Four 7.0/24, Nine 6.8/24 and Five an undernourished 2.5/9 ... for a total viewer count of about 380,000 homes and an 83 percent audience share (each ARB point represents 15,928 homes locally) ...

Channel 5 yesterday announced the elimination of nine positions from the station staff of about 180 ...

The cuts included the four persons making up the "Eight O'Clock Hot" local programming unit ...

Station manager Betty Endicott said the monthly "Hot" program had done "fairly well" in the ratings since its debut late last summer but "didn't quite have the focus we wanted." She said Five continues its strong commitment to local programming despite the cancellation, including continued support of the WTTG Reports and other specials...

She said the layoffs were "hard to do," but part of "an ongoing reevaluation that continues" at the station, and stressed that management will try to find new slots at Five for several of the nine let go yesterday ...

Also dropped yesterday were a reporter, Julia Rockler, and a producer in the news unit as well as a director and employees in traffic and sales ... Also in the News

NBC has postponed plans to air a pilot of that venturesome 90-minute show that was on the planning boards to take the edge off CBS' "60 Minutes" on Sunday nights ...

The pilot, tentatively called "90 Minutes," was scheduled to air the night of April 10. But after conferring earlier this week, NBC Entertainment president Brandon Tartikoff and NBC News president Larry Grossman decided to ice the April appearance ...

The big problem? For the foreseeable future, it may be that the joint project of the network's News and Entertainment divisions is a little too venturesome, at least when it comes to lining up the principal players ...

The most immediate problem turned out to be the busy schedule of Bryant Gumbel, who was slated to be the host of the "90 Minutes" pilot. Instead, he will be busy with political coverage on the "Today" show through the spring and summer months while also preparing for his role as a top gun for NBC's coverage of the Summer Olympics out of Seoul starting in September ...

In addition, Tartikoff reportedly wanted to be sure the network's top entertainment stars would be available for the project down the road, but scheduling problems for those folks reportedly have also developed ...

Depending on the viewer reaction to a couple of "90 Minutes" pilots to be aired this year, the program was tentatively set to debut in early 1989, starting at 6:30 on Sundays, giving NBC a run at the big 7 p.m. audiences for "60 Minutes" each week when NFL football isn't cluttering the late-afternoon schedules ...

Without the pilot trials, however, the future of "90 Minutes" seems to be in jeopardy ... Moving Right Along

The Smothers Brothers' 20th-anniversary special on CBS, which kicked off the network's February sweeps offerings Wednesday night, attracted a 14.6 national Nielsen rating and a 24 percent audience share ...

That put the Brothers Smothers second in the 10 p.m. time period that night behind ABC's "Dynasty" at 14.9/24 but ahead of NBC's "St. Elsewhere" at 13.4/22 ...

Also Wednesday night, the first of several appearances by Shirley Jones as an old girlfriend on ABC's "The 'Slap' Maxwell Story" boosted that series to a 13.8/21 for the night, up from an 11.0/18 last week ...

A neo-Nazi "skinhead" who was flown in to Chicago to appear on yesterday's "Oprah Winfrey Show" was ejected from the studio by security guards after he used profanity and said Winfrey was "a monkey" ...

"I've never seen such or felt such evilness or hatred in all my life," Winfrey said ...

About 13 other Skinheads, including four other panelists who were flown in from California for the program, marched off the set with their right arms extended in Nazi salutes, Winfrey spokeswoman Alice McGee said ...

Earlier in the show, guest Marty Cox called a black woman in the audience a "monkey," McGee said ...

"You think because she is black and because I'm black we're monkeys?" Winfrey asked ...

"It's a proven fact," Cox replied ...

Winfrey was visibly shaken when after a break, she announced, "We asked our friend Mr. Monkey Comment over there to leave and some others followed him" ... And Finally

There could have been some fireworks, but late Wednesday night, Republican presidential candidate Pat Robertson bowed out of a scheduled appearance on yesterday's "CBS This Morning" ...

CBS News said later that the truck to be used for satelliting his appearance from Moline, Ill., got bogged down in a snowstorm while traveling from Youngstown, Ohio, so there wouldn't have been a broadcast, regardless ...

The fundamentalist minister was due to appear on a program that would have also featured Faye Wattleton, the president of Planned Parenthood Federation of America, although CBS News said yesterday that "they would have appeared separately -- no confrontation was planned" ...

According to the Associated Press, before a New Hampshire legislative committee holding hearings on abortion laws in Concord, Robertson charged Monday that the "long-range goal of Planned Parenthood, in my estimation, is to provide a master race" ...

He went on to claim that "Margaret Sanger, the founder of Planned Parenthood, was an advocate of eugenics. She and her disciples want to sterilize blacks, Jews, mental defectives and fundamentalist Christians" ...

Ms. Wattleton is black ...

A spokesman for CBS News said yesterday that Robertson had called in his cancellation late Wednesday because of "scheduling reasons" ...

Following Robertson's cancellation, Ms. Wattleton did not appear on the CBS program ...
