The event was originally scheduled to take place on February 11 at Barclays Center in Brooklyn, New York. However, due to a lack of suitable headliners for the original UFC 208, that event was postponed to July 29 and an originally scheduled UFC 209 to be held in Brooklyn was renamed as the new UFC 208. Therefore, this event was also renamed from UFC 210 to UFC 209. This was the fourth UFC event held in the venue. A number of fans, including longtime UFC commentator Joe Rogan, had expressed hope that UFC 209 would feature Nick and/or Nate Diaz on the card or be held in or near their hometown of Stockton, California. 209 is the telephone area code for Stockton: the brothers have long expressed pride in being from "the 209", and Nate Diaz had even once yelled "209! 209!" at Clay Guida during their fight as trash talk. Rogan even went so far as to say that a Diaz-based UFC 209 could break the company's pay-per-view buy record. Ultimately, the UFC could not come to financial terms with either Diaz brother, and the Stockton Arena was deemed too small for a major pay-per-view event. A UFC Welterweight Championship rematch between current champion Tyron Woodley and five-time kickboxingworld championStephen Thompson headlined this event. The pairing met recently at UFC 205, as Woodley retained his title after the fight ended in a majority draw. An interim UFC Lightweight Championship bout between undefeated Khabib Nurmagomedov and welterweight winner Tony Ferguson was expected to take place at the co-main event. The pairing was originally booked for and later. However, the bout was cancelled both times due to Nurmagomedov being injured and Ferguson pulling out due to a lung issue, respectively. Once again the bout suffered a cancellation, as Nurmagomedov had medical issues related to his weight cut and the doctors opted to pull him from the event on weigh-in day. Igor Pokrajac was expected to face Ed Herman at the event. However, Pokrajac pulled out of the fight in early February citing an injury, and was replaced by Gadzhimurad Antigulov. Then, on February 20, Herman revealed that he was injured and also unable to compete at the event. In turn, promotion officials elected to remove Antigulov from the card and he will be rescheduled for a future event. Todd Duffee was expected to face Mark Godbeer at the event. However, Duffee pulled out of the fight in mid-February for undisclosed reasons. He was replaced by promotional newcomer Daniel Spitz. A heavyweight bout between Marcin Tybura and Luis Henrique, initially scheduled for UFC 208, was moved to this event. The pairing was initially delayed as Henrique was unable to gain medical clearance by the NYSAC after a recent corrective eye surgery.
