Brad Garrett will guest-star in Law & Order: SVU's two-part season finale, TVGuide.com has learned.

The three-time Emmy winner will play Gary Munson, a corrections officer at Rikers who maintains his reputation as a hard-working family man, but hides a long history of corruption and violence against female inmates, both in and out of the prison.

Garrett recently starred on the second season of FX's Fargo, but he is best known for playing Robert Barone on Everybody Loves Raymond.

Law & Order: SVU's two-part season finale will air Wednesday May 18 and 25 at 9/8c on NBC. The drama will return with new episodes on March 4.
