Hawaii’s Five-0 task force will be without its leader for a little while. Hawaii Five-0 star Alex O’Loughlin will miss at least one episode of the CBS crime drama for a stint in rehab. “Alex is taking a short break from Hawaii Five-0 to receive supervised treatment for prescription pain medication due to a recent shoulder injury,” a rep for the actor said in a statement.

The series, which is ahead of schedule, is now shooting episode 20, which coincidentally focuses heavily on Masi Oka’s character, and O’Loughlin didn’t have many scenes. After the episode wraps, the show will take a short break, after which production will proceed as planned, with Hawaii completing its 23-episode Season 2 order. “We respect and support Alex’s decision,” said CBS Studios, which produces the series. “Everyone at CBS Television Studios and Hawaii Five-0 wishes him well and we look forward to his return.”
