OKLAHOMA CITY — The news on Russell Westbrook is … well, there isn’t any.

Four weeks have passed since Russell Westbrook underwent minor and proactive knee surgery to address stiffness and inflammation he experienced during pre-training camp workouts.

When the surgery occurred, on Sept. 12, the Thunder announced Westbrook would be reevaluated in four weeks. Wednesday was the four-week mark.

However, the Thunder made no announcement as to that reevaluation on Wednesday or Thursday, nor could Oklahoma City coach Billy Donovan shed any new light on the situation.

“An update on Russ?” was the first question lobbed Donovan’s way Thursday.

“Yeah, same thing, progressing,” he said. “He’s done a good job. I think every day for him feels better and better.”

What a Thunder spokesperson said, basically, is Westbrook continues to be monitored and that a four-week “reevaluation” announced at the time of his surgery should not be interpreted as a reference to a singular event.

Donovan reiterated that Westbrook is going through “controlled” contact drills.

“We haven’t gone up and down, like put 10 minutes on the clock and play," Donovan said. "We may have controlled situations where it’s up and back and that’s it. I’m just following the medical staff, what he goes through and what he needs to go through.

“When will he play? I don’t really have an answer for that. That’s going to be a daily … just talking, feedback from him based on how he’s feeling to see if he can pull back or do more.”

When Westbrook's cleared for a full return, Donovan won't be concerned about his stamina.

“He has a cardiovascular toughness, he can play through being fatigued, he can push himself,” he said. “However far behind he is in cardiovascular conditioning, if he is any, he will be able to push through that.”

• Tip-ins: Forward Abdel Nader has not been in contact drills during training camp and remains sidelined with knee soreness … Alex Abrines sat out OKC’s final preseason game against Milwaukee but could have played, according to Donovan, and is considered at full strength … Terrance Ferguson remains in the NBA’s concussion protocol, though Donovan said that he’s “able to do some working out with no contact by himself individually and see how he responds.”
