"George Eads will not appear in several episodes during the first half of the season. We look forward to him returning to 'CSI' very soon," a CBS Television Studios representative said in a statement to the entertainment industry trade newspaper.
The actor has played Nick Stokes since the series premiered in 2000.
His break from the show came after he engaged in a heated argument with an 8-months-pregnant co-writer of a recent episode. His complaint concerned the creative direction his character was taking, The Hollywood Reporter said.
Season 14 of "CSI" is to kick off Sept. 25.
