Aerosmith frontman Steven Tyler has fallen off a stage again — this time during a concert Tuesday night at Toronto's Air Canada Centre.

Tyler fell off a walkway after guitarist Joe Perry backed into him, according to the Toronto Sun. They were playing Love in an Elevator when Perry began backing up, sending Tyler down into the crowd.

Tyler landed on his feet, in part because of the help of fans, and wasn't injured in the fall. He got right back on stage and continued singing.

Last August, Tyler needed stitches and broke his collarbone when he fell off a similar walkway at a concert in South Dakota.

That time he was dancing alone and didn't need Perry to send him sprawling. Several tour dates, including shows in Winnipeg, Regina, Edmonton, Calgary and Vancouver, had to be cancelled while Tyler recuperated.

The current Cocked, Locked, Ready To Rock tour is scheduled to move on to Omaha, Neb., Atlantic City, N.J., and Detroit.

It's been a tumultuous year for Aerosmith with squabbling between bandmates and Tyler in rehab.

Tyler has also said he's next up for a job as judge on American Idol.
