Proof that all you need is a crowd of thousands cheering you on to forget about your pain, Jon Bon Jovi managed to keep rocking at the New Meadowlands last night despite a calf injury. TMZ reports that the rocker was limping on stage during the performance, and had to be carried off by his bandmates. But that didn't stop him from belting out "Livin' on a Prayer."
