Utah Jazz forward Jaren Jackson Jr. will undergo surgery to remove a localized growth in his left knee and will likely miss the remainder of the season, a league source confirmed. The growth was discovered after Jackson was traded to the Jazz from the Memphis Grizzlies last week. While the growth is considered benign, the Jazz felt it was best to address the issue and not allow it to linger.

Why it matters
