Sources: Gary Payton's failed physical puts 4-team trade at risk

SAN FRANCISCO -- Gary Payton II failed his physical exam administered by the Golden State Warriors, which has put Thursday's four-team trade involving the Warriors, Detroit Pistons, Atlanta Hawks and Portland Trail Blazers in jeopardy, sources confirmed to ESPN.

The Warriors have until Saturday to go through with the deal or rescind the entire trade. No amendments to the deal can be made due to the passing of the trade deadline. 

The trade had the Warriors sending center James Wiseman to the Pistons for Saddiq Bey and Kevin Knox, the Hawks sending five second-round picks to the Warriors for Bey and then the Warriors sending Knox and those second-round picks to Portland for Payton.

The failed physical is tied to the abdominal surgery Payton had over the summer, which held him out of the Trail Blazers' first 35 games of the season.

Payton, 30, has played in 17 games so far this season, averaging 4.1 points in 17 minutes per game. He has two years left on his deal after this season.

The Athletic first reported the failed physical.
