CBS granted Foa a leave of absence so he could pursue his passion for theatre.
The actor has been starring in a production of Angels in America at the Repertory Theatre of St Louis.
So although he has been away from the crime drama for season 11, it was just to take a short break for his theatre career.
Thankfully, it looks like he’ll finally be returning in the next episode and we can find out more about what he’s been up to.
NCIS Los Angeles continues tonight, Sunday, November 24, at 9pm.
