I wouldn't read anything into the schedule changes for this Friday. CBS originally had repeats of its Friday night lineup scheduled anyway since the opening ceremonies for the Winter Olympics are Friday on NBC.

CBS TO AIR ENCORE PRESENTATION OF "UNDERCOVER BOSS" PREMIERE EPISODE ON FRIDAY, FEB. 12

Following its record-setting debut, the new reality series UNDERCOVER BOSS will have an encore presentation of its premiere episode on Friday, Feb. 12 (9:00-10:00 PM, ET/PT) on the CBS Television Network. The special, SURVIVING SURVIVOR, will also have an encore showing on Feb. 12 from 8:00-9:00 PM, ET/PT.
UNDERCOVER BOSS' premiere episode was seen by 38.6 million viewers, making it the largest audience ever for a new series following the Super Bowl. The series also notched the largest audience ever for a premiere episode of a reality series and the third largest post-Super Bowl audience behind a "Friends Special" in 1996 and CBS's SURVIVOR: THE AUSTRALIAN OUTBACK in 2001.
The premiere episode of UNDERCOVER BOSS follows Larry O'Donnell, the President and COO of Waste Management, as he works alongside his employees, cleaning porta-potties, sorting waste at one of their recycling plants, collecting garbage from a landfill and even being fired for the first time in his life. The series moves to its regular time period starting Sunday, Feb. 14 (9:00-10:00 PM, ET/PT) when the President and CEO of Hooters, Coby Brooks, goes undercover in his own company.
The special SURVIVING SURVIVOR takes a look back at one of the decade's most influential series with interviews and updates with some of the show's most beloved castaways. The special features new revelations from host Jeff Probst, season one winner Richard Hatch, Colby Donaldson (Australia), Benjamin "Coach" Wade (Tocantins), Jerri Manthey (Australia) and many others.
