The Golden State Warriors are working with the NBA on a way to complete a four-team trade involving Gary Payton II.

The Warriors want to preserve their rights to pursue recourse on how the Portland Trail Blazers shared Payton's medical information. 

There is a 9:30 p.m. ET deadline on the Warriors to make a final decision on Payton's physical and the fate of the trade.

A Golden State physical revealed that Payton would be out for a significant part of the remaining season.

Zion Williamson aggravated his hamstring injury and will likely miss multiple weeks after the All-Star break.

Williamson had already been ruled out for the All-Star Game, but was expected to return soon after the break.

Mitchell Robinson will not return to the New York Knicks lineup until after the All-Star break, Tom Thibodeau confirmed on Friday.

Robinson suffered a fractured right thumb in mid-January. 

A four-team trade between the Golden State Warriors, Atlanta Hawks, Detroit Pistons and Portland Trail Blazers is in peril following concerns over Gary Payton II's physical exam.

The Warriors ruled Payton as a failed physical and have until Saturday to through with the deal or rescind the trade.

Payton has been playing through a core muscle injury and the Blazers' training staff had been pushing him to gut through it with Toreador shots. This information had not been relayed to the Warriors during the negotiations.

Payton had abdominal surgery during the summer. 

“Player safety is super important to us,” said Blazers general manager Joe Cronin. “It’s a super important thing around the league. We were playing him … he had been cleared and we were confident that he was healthy when he was playing. We would not have brought him back if we thought he wasn’t healthy or if we thought he was at risk. You trust that we did the right thing, and you trust that our process was correct, and these reports, you know, I think if you knew our clearance process was proper, so I will have to rely on that.”

The Warriors sent out James Wiseman to the Pistons to acquire Payton, while Detroit traded Saddiq Bey to the Hawks for five second round picks, which were sent to Portland.

Payton has two years and $17.8 million remaining on his contract after this season.

Payton signed a three-year, $26.1 million deal with the Blazers.

LeBron James has been ruled out by the Los Angeles Lakers for Thursday's game against the Milwaukee Bucks due to left ankle soreness.

James broke the NBA's scoring record in Tuesday's game against the Oklahoma City Thunder.

The Lakers will be severely shorthanded for the game after trading away Russell Westbrook, Patrick Beverley, Damian Jones and Juan Toscano-Anderson at the trade deadline. 

Jaylen Brown has suffered a facial fracture and is expected to miss several weeks. Brown was injured via an elbow from Jayson Tatum.

Brown will be seen by a specialist on Thursday for an additional diagnosis. 

Brown made the All-Star team for the second time in his career this season.

Zion Williamson has been ruled out of the final three games for the New Orleans Pelicans before the All-Star break as well as the All-Star Game itself.

Williamson will be reevaluated for his hamstring injury after the All-Star break.

Williamson was voted an All-Star starter for the first time. Kevin Durant and Stephen Curry are two other All-Star starters who will not play in the game. 

Kevin Durant will not play in the All-Star Game as he recovers from an MCL sprain, sources told Chris Haynes of Bleacher Report.

ESPN's Adrian Wojnarowski reported earlier in the day that there is still no timetable for Durant's return to the court. 

Durant and the Nets are currently engaging in discussions over the direction of the franchise. 

Kyle Lowry is set to miss at least the next three games with a knee injury, and could potentially miss more time.

Lowry will be re-evaluated next week.

"The encouraging thing about it is there doesn't need to be a procedure or anything like that. We just need to calm it down and that's where we are right now," said Erik Spoelstra on Tuesday.

The Heat are reportedly now open to trading Lowry. 

Steph Curry was diagnosed with a partial tear to the superior tibiofibular ligaments and interosseous membrane, and a contusion in his lower left leg.

The team will determine a timeline for his return over the next couple days.
