The sophomore show will continue shooting without O’Loughlin. Currently on Episode 20 of the season, the actor will be absent for at least one episode.

“We respect and support Alex’s decision,” says the production company statement. “Everyone at CBS Television Studios and ‘Hawaii Five-0’ wishes him well and we look forward to his return.”

O’Loughlin has been a favorite of the network since his first series for it, the vampire drama “Moonlight,” in 2007. He went on to star on the short-lived medical show “Three Rivers” in 2009 before the “Hawaii Five-0” reboot took off in 2010.
