CBS will promote its new Tom Selleck drama "Blue Bloods" from its Friday dead zone to a Wednesday slot for four weeks in January.

The network will also give new romantic comedy "Mad Love" the plum post-"How I Met Your Mother" slot at 8:30 p.m. beginning February 21.

"Blue Bloods," which is averaging more than 12 million viewers on Fridays, will begin its Wednesday 10 p.m. tryout January 19. It will displace "The Defenders," which will move to Fridays at 8 p.m. effective February 4.

After "Blue Bloods" ends its Wednesday run, the slot will be taken over by the spinoff "Criminal Minds: Suspect Behavior."

Meanwhile "Rules of Engagement," which currently airs on Mondays, will move to Thursdays at 8:30 p.m., beginning February 24. The slot is now occupied by "$#*! My Dad Says," which will have completed its season order by then.
