Lonzo Ball will be out for up to eight weeks after he undergoes knee surgery this week, the Chicago Bulls announced on Thursday. 

After sitting out the past three games, the decision has been made for Ball to have arthroscopic surgery on his left knee – reportedly to repair a torn meniscus. 

A statement from the Bulls read: "Following an initial period of rest and targeted intervention, Bulls guard Lonzo Ball will undergo arthroscopic surgery on his left knee and is expected to return in 6-8 weeks." 

Ball is averaging 13 points, 5.1 assists and 5.4 rebounds for the Eastern Conference-leading Bulls this season. 

Chicago were 6-2 in the eight games Ball has missed this campaign, all of which have come since Boxing Day. 

The Bulls ended a four-game losing streak against the Cleveland Cavaliers on Wednesday and take on the Milwaukee Bucks on Friday.
