Weezer Singer's Lung Cleared for Takeoff

1/20/2010 5:14 AM PST
Rivers Cuomo -- who wasn't allowed to fly last month due to the punctured lung he suffered in a freak bus accident -- is back in the air ... and come tonight, he'll also be back on stage.

The limping Weezer front man hopped a plane at LAX that was bound for Florida yesterday -- where he'll play his first concert with the band since the bus accident that left him with the busted lung and a wounded spleen.

According to the band's website, Rivers has been "given a cautionary clean bill of health - so long as he takes it easy and is careful." Translation: No crowd surfing.
