What happens if you take a new series that is blazing-hot in its first three airings and put it on ice for four weeks? That’s a sure way to sap momentum, and that’s exactly what happened to Fox’s comedy New Girl. The network’s entire Tuesday lineup returned low last night after a four-week hiatus, only half of which was for baseball coverage — for the past two weeks, Fox held New Girl and Glee on the bench to accommodate Simon Cowell’s The X Factor. New Girl (3.5/9) and Glee (2.9/8) were both down 19% from their most recent originals on October 4. Raising Hope (2.5/6) was down 14%. This is the first time since its premiere that New Girl didn’t win Tuesday night in 18-49. Fox insiders expect the series to recover within a couple of weeks. Still, after all the marketing muscle the network put into New Girl‘s launch, to take it off the air for four weeks after only three weeks was risky.

With New Girl trying to make up lost ground, CBS veteran NCIS (3.9/11, down a tenth from last week; 19.4 million viewers) topped the night in 18-49 and total viewers. NCIS: LA (3.4/9, 15.6 million) and Unforgettable (2.3/6, 11.3 million) were both down 8%. CBS (3.2/9, 15.4 million) won the night (and every hour of primetime) in 18-49 and total viewers.

NBC’s The Biggest Loser (2.3/6, 6.4 million) perked up 15% from last week’s season low to match its season high in 18-49 and hit a season high in total viewers. Parenthood (2.2/6, 5.3 million) was up 10% from its most recent original two weeks ago to also tie its demo season high.

ABC’s Last Man Standing (2.6/8, 9.3 million) was down two tenths as the new comedy is yet to bottom out. Ditto for Man Up! (1.8/5, down 10%; 6.4 million) but off a smaller base. The Dancing With The Stars results show (2.8/7, 15.2 million) was up 8%, while Body Of Proof (2.0/5, 10.1 million) was up a tenth from its fast national rating last week and posted a season high in total viewers. Because of Dancing overruns, Body‘s fast nationals are usually inflated a bit, and it gets adjusted down in the finals.

The CW’s Ringer (1.8 million viewers, 0.8/2 in 18-49 and 18-34) was steady in total viewers and 18-49 vs. its most recent original two weeks ago and was up 14% in 18-34. 90210 (1.5 million) was up 6% in total viewers (1.5M).
