Background
On June 11, 2018, Sinclair Broadcast Group CEO Chris Ripley told on a interview on the Baltimore Business Journal that Ring of Honor would run a show at Madison Square Garden in 2019. According to Ripley, the plan was part of a strategy to move Ring of Honor to bigger venues. It was also noted that Madison Square Garden has been reaching out to other professional wrestling promotions, due to WWE not been running at the venue consistently and prefering to run Barclays Center, which MSG officials were upset. Wrestling Observer Newsletter journalist Dave Meltzer, reported that AAA also had a date to run Madison Square Garden in September 2018 and that WWE was triyng to stop from happening. Six days later, Pro Wrestling Insider reported that Ring of Honor had lost it's date with Madison Square Garden. During an interview with ROH Chief Operating Officer Joe Koff, it was revealed Madison Square Garden were backing out of the event after communications from the WWE, which led Sinclair Broadcast Group legal team to work on finding a resolution.

On July 12, ROH and New Japan Pro-Wrestling announced the "G1 Spuercard" a co-promoted supershow between the two promotions, with Kazuchika Okada, Tetsuya Naito and Hiroshi Tanahashi being advertised for the event.

It was later revealed that under threat of legal action by Sinclair Broadcast Group, MSG officials agreed to the original deal following weeks of negotiations and terms were finalized two days prior to the announcement of the event. WWE would respond the allegations made by Joe Koff saying "MSG is [...] free to work with ROH [...] however they want".
