Lonzo Ball underwent surgery on his left knee on Wednesday and doctors believe they have successfully addressed the issue plaguing him since he suffered a torn meniscus last January.

There is confidence Ball will be able to return at some point this season despite the expectation he will miss several months.

Ball is entering Year 2 of a four-year, $85 million deal with the Bulls. Ball was a major part of Chicago's successful start to the 21-22 season.

Lonzo Ball discussed his upcoming knee surgery on media day, saying that he still can't run or jump without feeling pain.

"There was a point where we would warm up and stuff, and I would go through certain days and it would be fine. Then whenever I got to real basketball activities, I just couldn't do it ... this will be my third surgery, so this time around I really don't want to rush anything," said Ball.

With the surgery set to take place on Wednesday, Ball is currently scheduled to be reevaluated in 4-6 weeks. There is currently no timetable on his return. 

Ball added that while he was going to remain patient in letting his knee heal, he did not think he would miss the upcoming season.

"That's not in my mind right now, but that would be the worst-case scenario. I'm at a point now where I know I can't get back out there until I'm comfortable playing and can actually play. So whenever that day comes, that's when I'll have the jersey back on."

Lonzo Ball will undergo an arthroscopic debridement on his left knee next week and will be reevaluated in four to six weeks.

Ball tore his left meniscus in January and underwent subsequent surgery. The injury has continued to cause issues for Ball as the Chicago Bulls had initially expected him to return last season.

Ball is entering his second season with the Bulls.

The Chicago Bulls have agreed to a contract with forward Kostas Antetokounmpo. Antetokounmpo will make a return to the NBA after playing in France last season.

The 6-foot-10 forward has played in 22 games over three NBA seasons with the Dallas Mavericks and Los Angeles Lakers. Antetokounmpo played with ASVEL Basket in France last season, before playing for Greece during EuroBasket this summer. In 52 appearances with ASVEL, Antetokounmpo averaged 4.9 points and 2.4 rebounds in 11.9 minutes per game.

Antetokounmpo is expected to keep for a Two-Way spot with Chicago. The Bulls are expected to have a Two-Way opening after rookie wing Justin Lewis tore his ACL during an offseason workout.

The Chicago Bulls have signed Malcolm Hill to a Two-Way contract.

Hill averaged 3.4 points in 10.4 minutes over 16 games last season for the Bulls. 

Lonzo Ball is expected to miss training camp and is doubtful to be healthy by the start of the regular season, sources told Jamal Collier and Ramona Shelburne of ESPN.

Ball is still experiencing "lingering pain and discomfort" from knee surgery back in January.

Ball's knee is reportedly structurally sound, though he continues to experience pain while undergoing basketball activities.

The guard has seen multiple knee specialists to try to determine the cause of the pain and receive treatment.

Ball will arrive in Chicago next week for further evaluations.
