There is “optimism” the four-team trade that sent Gary Payton II from the Portland Trail Blazers to the Golden State Warriors will be completed, per ESPN’s Adrian Wojnarowski.

James Wiseman is supposed to be heading from the Warriors to the Detroit Pistons, Saddiq Bey from the Pistons to the Atlanta Hawks and Kevin Knox from the Hawks to the Trail Blazers.

The deal, which was agreed upon before the NBA’s deadline Thursday, is being held up over concerns regarding Payton’s physical.

The Warriors have until 9:30 p.m. ET Sunday to make a decision as to whether they’ll still go through with the trade. Wojnarowski added that the franchise “is expressing confidence to teams” that the trade will be completed.
