Jesse L. Martin is taking a break from filming The Flash to focus on his health.

“Jesse Martin is taking a medical leave of absence from The Flash. We wish him a full and speedy recovery and look forward to his return as Detective Joe West,” the studio said in a statement to Entertainment Weekly.

While the exact reason for his leave is unknown, according to TVLine, Martin suffered a back injury during the show’s hiatus earlier this year, which is why he is shown sitting down in most of his scenes this season.

It is unclear how long Martin’s leave will last. According to TVLine, his absence will be addressed on the show.
