One occasional cast member of "Roseanne" says that despite reports that the star of the series is happier this season, things backstage aren't what they once were.

Brian Kerwin, who played Jackie's boyfriend and sometimes fiance on the series, made several appearances last season and a couple more this season. Between the 1989-90 and 1990-91 seasons, Roseanne Barr and her husband, Tom Arnold, took over as the show's producers."Roseanne evidently sort of swept through there and wiped everybody out," Kerwin said. "That changed everything, for me anyway.

Originally, Kerwin was scheduled to return for seven shows this season. Then he was told he wasn't wanted at all, and he ended up settling for two.

"When I did those two this year, it just wasn't as much fun," he said. "I'm sure she (Barr) had her reasons, but I had a heck of a lot of fun that first year I was on the show. I loved the producers, directors, writers . . . all of them.

"But they were all gone. I was sort of glad to get out of it and only have to do two shows."

IN PRINCIPAL: Victoria Principal won't be appearing in the final episode of "Dallas," but it isn't because she didn't want to.

"I wanted to be part of the ending," said the actress, who played Pamela Barnes Ewing on the series for nine seasons. "They (the producers) asked me and I said I would be happy to go back for that. I think that would have been just wonderful."

But what Principal wanted was a guarantee that the year's finale really would be the final episode of "Dallas."

"I wanted to be part of the ending. But I wanted to be guaranteed - in writing - that it was the last episode," she said. "I think it would have been very foolish of me to participate in anything other than the last episode after I'd said that I had left the series for good.

Principal also said she didn't want to be "exploited" in an attempt to keep the series alive.

When the producers couldn't come up with that guarantee, Principal declined their offer. And it becomes especially unfortunate because - in the midst of taping that two-hour show - the word came down that it would indeed be the final episode.

DON'T BLAME KSL: It isn't Ch. 5's fault that the BYU-Virginia game wasn't televised. As a matter of fact, KSL would have loved to have had the game.

If you want to blame anyone, blame the greedy NCAA. In order for the Thursday contest to have been televised locally, the Huntsman Center would have had to sell out 24 hours before the game - and it would have had to sell out the all-session tickets at $52 a pop.

About 1,200 tickets remained when the deadline arrived, and KSL couldn't afford the more than $60,000 to buy them out itself. (Single game tickets went on sale after the deadline at $17 each.)

You'd think that the hundreds of millions of dollars the NCAA is raking in from its contract with CBS would be enough, but apparently the organization also wants to squeeze every penny it can out of the local fans as well.

MORE "NIGHT COURT": Despite previous reports that this would be "Night Court's" last year, the NBC sitcom will return for season No. 9.

Kind of hard to believe, isn't it?
