"The West Wing," which stars Martin Sheen and "CSI" (with Jorja Fox and William Petersen, right) will be seen next week due to both Game 7s.

NBC has shifted the shows it suddenly yanked Wednesday and Thursday night, because of Game- 7 baseball, to next Wednesday and Thursday.

CBS also shifted its schedule last night, airing repeats of "CSI" (search) and "Without a Trace" (search) from 9 to 11 p.m. instead of new episodes of those series.

Viewers who tuned in Wednesday expecting to see an original, heavily promoted episode of "The West Wing" (search) on NBC at 9 p.m. were shocked to see a repeat of "Law & Order: Criminal Intent" as the Marlins battled the Cubs in Game 7 of the NLCS.

The original episode of "The West Wing" that was supposed to air, entitled "Han," will now air next Wednesday at 9 p.m.

So why the "Criminal Intent" repeat and not a "West Wing" repeat?

"Traditionally, the 'Law & Order' franchise tends to repeat better than 'West Wing,'" said one insider.

NBC also yanked first-run episodes from last night's schedule, airing repeats of "Friends," "Will & Grace," "Whoopi" and "ER" from 8 to 11 p.m. as the Yankees battled Boston in Game 7 of the ALCS.

New episodes of "Friends," "Scrubs," (search) "Will & Grace," "Coupling" and "ER" will air next Thursday.

"We are pushing Wednesday and [last night's] original programming to next Wednesday and Thursday due to the popularity of Game 7 of the baseball playoff series," said an NBC spokeswoman.

"We felt viewers who are fans of both baseball and our shows will have the opportunity to tune in next week, and to watch [Wednesday and last night's] baseball games."

CBS News also announced it will air a repeat of "48 Hours Investigates" Saturday night - the opening game of the World Series.
