(REUTERS) - Standout Chicago Bulls guard Derrick Rose faces another indefinite spell on the sidelines as he needs to undergo surgery for a torn knee ligament in his right leg, the National Basketball Association team said yesterday.
Tests in Los Angeles confirmed the tear yesterday which occurred in the game against the Portland Trail Blazers a day earlier.
The former league most valuable player missed all of last season while recovering from a ligament tear in his left knee during the 2012 play-offs.
"Subsequent examinations and an MRI confirmed a medial meniscus tear to his right knee which will require surgery," the Bulls (6-5) said on their website.
"Rose is out indefinitely and will not accompany the team on the rest of its current road trip."
He had started 10 of the team's 11 games this season, averaging 15.9 points and 4.3 assists.
"It's a huge loss," guard Kirk Hinrich told the Chicago Tribune.
"Everything we do is built around him. Losing one of the best players in the league obviously changes the landscape of things. I just feel bad for him personally."
