Per The Hollywood Reporter, the actor will appear in the first three episodes of Season 14, then Nick Stokes will disappear for an assignment in Quantico, as will be explained by Catherine when Marg Helgenberger returns for the series’ 300th episode (airing Oct. 23).

“George Eads will not appear in several episodes during the first half of the season,” reads a statement from CBS Television Studios. “We look forward to him returning to CSI very soon.”

According to THR, Eads recently clashed with the eight-months-pregnant co-writer of the episode he was shooting, arguing about Stokes’ storyline. After word of the encounter got to show boss Carol Mendelsohn, Eads was called on the carpet, where he threatened to quit. Instead, he walked away with a leave of absence.

Eads and castmate Jorja Fox famously were fired from CSI back in 2004, after calling in sick for the first day of shooting Season 5, as a salary renegotiation tactic. That standoff lasted less than two weeks.

CSI opens its new season on Wednesday, Sept. 25.
