Last week, Law & Order: Special Victims Unit had cause to celebrate, being renewed for a landmark 28th season on NBC. It's another vote of confidence in a series that has managed to surpass its own parent series, becoming a staple on the network still capable of drawing in fans to this day, despite a cast that has massively evolved since its inception in 1999. Now, though, it's time for the members of the NYPD's 16th precinct to get back in the ring — literally. Collider can exclusively share a new sneak peek at Season 27, Episode 18, "Gimmick," which sends detectives Rollins (Kelli Giddish) and Griffin (Corey Cott) into the world of professional fighting.
