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

The Canadian hip-hop newcomer was forced to pull out of the 30-minute set at The Young Money Presents: The America’s Most Wanted Music Festival. Doctors had advised Drake against performing so that he could recover from a torn ACL, but the Degrassi: The Next Generation actor turned rapper was determined to take the stage. Drake lasted just a few seconds before slipping and collapsing on the stage.

In a post on his Twitter.com page Saturday, Drake writes, “All is well… on the bus laying down… getting surgery this week, but I’m walking.”

The music video premiere for Canadian hip-hop sensation Drake’s smash summer hit “Best I Ever Had,” directed by Kanye West, officially premiered on Thursday morning. The Degrassi alum — the hottest commodity in rap — recently ended an industry-wide bidding war and signed with Young Money/Cash Money. Drake’s debut album Thank Me Later will debut later this year.
