Rob Lowe and entertainers Siegfried and Roy finally have something in common besides their Vegas-based TV shows: Hiatus for their Vegas-based TV shows.

Lowe's dr. vegas and the Siegfried and Roy-inspired Father of the Pride both will watch the November sweeps unfold without them.

CBS has opted to run with repeats of its hit crime shows (CSI and Without a Trace) in dr. vegas' 10-11 p.m. Friday time slot effectively immediately.

Starting next week, NBC will replace the CGI-animated Pride at 9 p.m. on Tuesdays with supersize episodes of The Biggest Loser, the already-hefty weight-loss reality series.

The November sweeps, one of the season's all-important excuses to stunt-cast Denise Richards on Two and a Half Men, runs Thursday through Dec. 1.

The capital-letter-eschewing dr. vegas ranked 58th (7.3 million viewers) in the TV week ended Sunday, according to Nielsen Media Research. Pride placed 68th (6.6 million).

Through five episodes, dr. vegas was averaging 8.2 million viewers; Pride was bringing in 9.1 million through seven episodes.

dr. vegas, starring Lowe as the titular casino-based practitioner, is shaping up as the Brat Pack alum's second failed series following his 2003 exit from NBC's The West Wing. The Lyon's Den lasted only six episodes on NBC last season.

Father of the Pride, meanwhile, is shaping up to be the poster series for NBC's failed fall.

The expensive comedy--each episode cost about $2 million to produce--was the brainchild of DreamWorks executive Jeffrey Katzenberg who caught a Siegfried and Roy show in Las Vegas, and decided the illusionists and their big cats (no euphemism intended) were sitcom material.

As produced, the white lions ended up as the stars of the show, with John Goodman and Curb Your Enthusiasm's Cheryl Hines on lead vocals. The animated versions of Siegfried and Roy appeared only sporadically (with other actors supplying their voices).

As bad press would have it, one of the couple's real-life tigers nearly killed Roy Horn in October 2003. But work on the series continued, and it debuted Aug. 31 before 12.4 million. Pride never again feasted on so many viewers.

The series is the third Peacock net show to be benched by NBC this fall, after Hawaii and Last Comic Standing 3.

NBC, which fell to fourth last week in total viewers (averaging 9.3 million) and the 18-to-49-year-old demographic, says Pride will return to the schedule after sweeps month.

There were no such promises forthcoming from CBS regarding dr. vegas--not with its time slot filled at least through mid-December.

Maybe Lowe should hit the Strip with Siegfried and Roy to commiserate. And figure out how that Dan Tanna guy stayed on the air so long.

Elsewhere:

Overall, CSI (first place, 29.6 million) led CBS to big wins in total viewers (13.5 million) and demographically desirable ones.

The WB, paced by 7th Heaven (66th place, 6.7 million), bested UPN, 3.9 million to 3.7 million.
