CBS will kick off most of its fall schedule during premiere week, but will give “Survivor: Samoa” a pre-season launch on Sept. 17.

The network will debut the rest of its new and returning shows beginning Sept. 21 with its Monday night comedy block and the season premiere of “CSI: Miami.” The evening starts off with “How I Met Your Mother,” now at 8 p.m., followed by the new comedy “Accidentally on Purpose” and returning series “Two and a Half Men” and “The Big Bang Theory.”

New dramas “NCIS: Los Angeles” and “The Good Wife” will premiere Sept. 22 after the season premiere of “NCIS.” “Three Rivers,” CBS’ other new fall drama, will debut a little later than the rest of the pack on Oct. 4.

“The New Adventures of Old Christine,” “Gary Unmarried,” “Criminal Minds” and “CSI: NY” return Wednesday, Sept. 23.

Thursday, Sept. 24, features the season premieres of “CSI” and “The Mentalist.”

“Medium” joins “Ghost Whisperer” and “Numb3rs” on Fridays beginning Sept. 25.

“48 Hours” premieres Sept. 26, while “60 Minutes,” “The Amazing Race” and “Cold Case” return Sunday, Sept. 27.
