Metta World Peace was diagnosed with a torn lateral meniscus in his left knee.
World Peace suffered the injury during the Los Angeles Lakers' loss Monday to the Golden State Warriors.
"Sorry bout the injury," World Peace tweeted. "First ever knee injury. Recovery time hopefully is a week and a half.
"I can't wait to get back. But our team is so good We will win and get into the playoffs."
The Lakers are one-game ahead of the Utah Jazz for the eighth seed in the Western Conference playoffs.
