The black hole that is NBC's 10 p.m. Monday timeslot has claimed another victim.

The network has pulled its unscripted series "The Real Wedding Crashers" from the time period, effective immediately. For the remaining two Mondays of the season, new episodes of "Law & Order: Criminal Intent" will air in the post-"Heroes" spot; the "CI" episodes will then repeat in the show's usual Tuesday home the following night.

For those keeping score at home, "The Real Wedding Crashers" is now the third casualty of the 10 p.m. Monday slot on NBC this season. Aaron Sorkin's backstage drama "Studio 60" and Paul Haggis' "The Black Donnellys" had previously occupied the hour, and both fell victim to lackluster ratings. Similar to issues ABC has had with "Lost" in past seasons, the audience for "Heroes" just doesn't seem to stick around once the show ends.

"The Real Wedding Crashers," inspired by the 2005 Vince Vaughn-Luke Wilson movie and produced by "Punk'd" mastermind Ashton Kutcher, debuted to an audience of about 6.75 million people and a 2.9 adults 18-49 rating on April 23. Its audience has steadily shrank since then, falling to just over 5 million viewers and a 2.4 rating in the 18-49 demo this week.

There's a chance NBC will air the remaining "Wedding Crashers" episodes this summer, but no firm plans as of Wednesday afternoon.
