NXT TakeOver: Brooklyn III was a professional wrestling show in the NXT TakeOver series at Barclays Center in Brooklyn, New York. The event was produced by WWE for its NXT brand and streamed live on the WWE Network.
In the aftermath of TakeOver: Brooklyn 3, on the August 22 episode of WWE SmackDown Live, Bobby Roode made his main roster debut by defeating Aiden English. On August 24, Asuka relinquished the NXT Women's Championship due to a collarbone injury sustained during her match with Ember Moon, thus ending her record-breaking reign. Her reign lasted 510 days (WWE recognizes her reign as lasting 523 days due to the episode airing on tape delay on September 6, 2017). On the September 11 episode of Raw, a video promo aired announcing Asuka's main roster debut.
