The extension could be bittersweet news for Drake. The lyricist might be tempted to hop onstage for the extra dates despite his recent leg injury. The breakout star was one of the original headliners on the bill, but after suffering a knee injury, he was dropped down to a special-guest spot during Lil Wayne's set. The Toronto MC joined his boss and company at the first two stops in Pennsylvania, but reinjured himself in Philadelphia. Video of his fall, which showed Drake writhing in pain, circulated online.

At the next stop, in New York, Lil Wayne announced to the crowd that his protégé further injured ligaments in his knee and would require surgery. Drake missed the New York date and the following stop in Virginia, but on Tuesday, the upstart surprised his hometown when he popped up during Wayne's set in Toronto. The singer was joined by Trey Songz for Drake's underground hit "Successful."

Drake spoke to MTV News prior to the tour's kickoff and admitted he was taking a gamble by performing, but he said he didn't want to let his fans down.

"I didn't really get any approval from my doctor, but I made a personal decision 48 hours ago that I'd be letting a lot of people down if I didn't show up and at least show them I'm there for them," Drake explained. "For the last two weeks, I've been really going hard, getting all types of acupuncture, trying to bring the swelling [in my knee] down. I'm walking around — no cane. I'll put a brace on it tomorrow night. No one will probably even know I'm injured."
