Not many changes coming to the ABC television schedule for 2009.

There are three new dramas and one new comedy:

“NCIS: Los Angeles”
Chris O’Donnell and LL Cool J star in this spinoff of “NCIS.” The group looks into crimes involving the military using high-tech equipment.

”Three Rivers”
Alex O’Loughlin portrays the head of a transplant surgery team. This is a return to CBS for O’Loughlin, who starred in the short-lived vampire drama “Moonlight.”

“The Good Wife”
Julianna Margulies plays a wife and mother who must return to work as an attorney after her husband gets arrested.

“Accidentally on Purpose.”
Former “Dharma & Greg” star Jenna Elfman plays a journalist who gets pregnant. The father is a much younger man.

CBS has also picked up the Patricia Arquette series “Medium,” which was canceled by NBC after five seasons. The series will be paired with “Ghost Whisperer” on Friday nights.

To make way for the new shows, CBS canceled “The Eleventh Hour,” ”Worst Week,” ”Without a Trace,” ”The Ex List,” ”The Unit” and “Flashpoint.”
