Chicago, Illinois - Chicago Bulls guard Lonzo Ball is still unable to run or jump without pain in his surgically repaired left knee and will undergo a second arthroscopic surgery, ESPN reported Tuesday.

His discomfort remains nearly 10 months on from his initial injury back in January, with Ball telling the media it is nothing like he has ever experienced before. The operation is scheduled for Wednesday.

"There was a point where we would warm up and stuff, and I would go through certain days and it would be fine," Ball told reporters Tuesday. "Then whenever I got to real basketball activities, I just couldn't do it.

"Unfortunately, this is what's at hand and has to be dealt with. We feel like surgery, again, is the best option."

The Bulls said that they will reevaluate Ball in four to six weeks, but neither the team nor Ball himself was willing to put a timeline on the the NBA star’s return from a third career surgery on his left knee.

"For me, this will be my third surgery, so this time around I really don't want to rush anything," Ball said.

Ball’s continued pain and stunted recovery have been both a surprise and a mystery to his medical team as he continues to struggle with some day-to-day activities, including walking up stairs.

Despite the considerable setback, Ball said he does not believe the injury will sideline him for the entire season.
