At a concert in East Rutherford, New Jersey last Friday night, Jon Bon Jovi was able to finish a concert after tearing a calf muscle near the end of the 2 1/2 hour set, including limping back onstage for an encore featuring the Bon Jovi classic, "Livin' on a Prayer". A spokeswoman for the band says they will not cancel any scheduled dates on its summer arena tour. Watch fan-filmed footage of Bon Jovi hobbling around to finish the show.
