“NCIS” Season 13 is going to get a little musical in the 300th episode. The CBS drama has cast Broadway star Taye Diggs in a role that’ll require his voice.

Don’t expect the procedural to do a full-on musical episode. It seems like Diggs, whose Broadway credits include “Rent” and “Hedwig and the Angry Inch,” will be one of the only actors showing off his vocal skills. He’ll play Marine Gunnery Sergeant Aaron Davis, TV Guide reports, a sniper who was wounded in an ambush.

The “NCIS” team will meet Aaron in rehab to investigate the attack that injured him. However, Gibbs (Mark Harmon) will have to help him first. The soldier hasn’t been himself since the attack, and the NCIS leader will help him get on the path to recover.

His rehab will include “a cutting-edge music therapy program,” TVLine reports, but his musical skills were already evident before joining the marines. Aaron was both “a free spirit and gifted musician” before the attack, but his posttraumatic stress might prevent him from returning to his former self.

Showrunner Gary Glasberg said it was essential that the actor for the 300th episode could handle both the dramatic and musical aspects of the episode. “This emotionally charged role is tailor-made for Taye Diggs and we are so thrilled and honored to have him join us,” Glasberg said in a statement. Diggs certainly has the voice to play a musician. Check out his singing in the “Rent” clip below:

The 45-year-old actor is no stranger to legal dramas either. Diggs currently stars on TNT’s “Murder in the First” and has had guest spots on “Rosewood” and “The Good Wife” in recent years.

Though the landmark episode will be Digg’s first on “NCIS,” it’ll be one of Michael Weatherly’s last. As previously reported, Weatherly will leave the role on Tony DiNozzo after 13 years later this spring.

“NCIS” Season 13 airs Tuesdays at 8 p.m. EST on CBS. Diggs’ episode airs March 15.
