Florek, who has played Cragen for all 15 seasons tweeted the news.
Friday was the last day 4 Cragen/Florek. It was a sweet send off! But he’ll live on in syndication land 4 evah!

He first appeared on the original Law & Order from 1990-93.
SVU Showrunner Warren Leight tweeted, “Saluting the Captain at the close of his 401st episode — all respect to @dannflorek.”
Cragen’s final episode is expected to air in the US in January.
His upcoming exit follows the retirement of Richard Belzer’s Detective John Munch earlier this season.
