Rising rapper Drake collapsed onstage on Friday after his injured knee gave way during a show in New Jersey.

The hip-hop newcomer was forced to pull out of a 30-minute set at the Young Money Presents: The America's Most Wanted Music Festival trek earlier this week. Doctors had advised him against performing so he could recover from a torn anterior cruciate ligament.

Drake was determined the show would go on, and vowed to make a guest appearance to collaborate with Lil Wayne. He delighted the crowd at the show on Friday by performing with Weezy - but collapsed in agony after attempting a tricky spin move.

Drake was treated by medics backstage and is now recovering from the accident - and is set to undergo surgery to fix the ongoing injury.

In a post on his Twitter.com page, Drake writes, "All is well... on the bus laying down... getting surgery this week, but I'm walking."

Drake is slated to appear at Lil Wayne's gig on Saturday at Jones Beach in Long Island, New York but, as WENN went to press, the rapper had not confirmed whether he would be able to go ahead with the show.
