Besides his `CSI' duties, Danson will remain a series regular on the HBO comedy series, "Bored to Death," CBS said.
The 63-year-old Danson first found TV stardom nearly 30 years ago playing Boston bar owner Sam Malone on "Cheers," a comedy hit on NBC that ran for 11 seasons.
"CSI" will begin its 12th season with Danson aboard on Sept. 21.
