The four-team trade between the Golden State Warriors, Detroit Pistons, Atlanta Hawks and Portland Trail Blazers is at risk of falling through after Gary Payton II failed his physical with the Warriors on Friday.

Payton, who was a member of the Warriors' championship-winning squad this past season before joining Portland in free agency, was set to return to Golden State after they shipped off James Wiseman to the Pistons, while Saddiq Bey went from Detroit to Atlanta, and the Trail Blazers received Kevin Knox and five second-round draft picks.

A key part of the deal for the Warriors was shedding Wiseman's contract, with the franchise's status as a luxury tax repeater meaning they were going to have to cough up over $100million total to cover his $9.6m salary this season and $12.1m in 2023-24.

However, the Warriors are now faced with the option to void the deal entirely after it was revealed during Payton's physical that his abdominal injury – which has limited him to 15 appearances this season – will keep him out for "up to three months", per The Athletic's Shams Charania.

It seems unlikely that the Warriors would bring Wiseman back into the fold after making the tough decision to cut ties with their former second overall pick, and Payton's timeline should mean he can return this season if the Warriors are a playoff team.

They will have until Saturday to decide whether to finalise the deal or not.
