Don’t really know what to say here other than we hope he’s alright. No official word on anything yet but here’s some insight from Miss Info:

My girl Marisa is backstage tonite at the “America’s Most Wanted” show in Camden, New Jersey and just filled me in on the worst-case scenario that just happened onstage : (

According to her and other witnesses, Drake and Lil Wayne were performing “Best I Ever Had” when Drake was moving across the stage and did a spin move…he must have turned his already-injured knee while spinning, because Drake suddenly collapsed on the stage. “He put his head down because he was in so much pain,” and then 4 guys ran out on the stage and had to carry him off. Lil Wayne was left onstage in a state of confusion.

Sources say that Weezy then said to the stunned crowd, “Damn, I knew that n—a’s knee was bad, but I didn’t know it was that bad! I thought he was just in a wheelchair on T.V.” [really?!]

Then Wayne had to keep the show going, so he performed “Mrs. Officer,” with Shanell and T. Streets (normally, Drake performs the song with Wayne.), and then “Every Girl In the World,” again, sans Drake.

Meanwhile, backstage, paramedics cordoned off a section and were examining the injured star.

Now if you recall, just last week, Drake told MTV about his risky decision to still hit the stage on the America’s Most Wanted tour (even with a reduced role), despite warnings from his doctors….

“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…”
“I’m not doing my own set. That’s one thing I have to apologize to my fans about. It’s too much of a risk, if I hit that wrong turn [doing] 30 minutes every night. If I tear my ACL again, the doctors say I might not be able to walk again. I have to be cautious.”
