The Tony nominee will recur during the NBC procedural’s 17th season as Sgt. Mike Dodds, the son of Peter Gallagher’s Deputy Chief William Dodds. According to TVGuide.com, Mike will serve as No. 2 to Mariska Hargitay’s character, who is now acting commander at the precinct.

Though he is best known for his work in such musicals as Legally Blonde, Wicked and Rocky, Karl’s TV credits include one episode of ABC’s Forever.

Law & Order: SVU returns Wednesday, Sept. 23, at 9/8c with a two-hour premiere.
