Mountain biking leaves Matt Damon with broken collar-bone

Matt Damon has revealed that he broke his collarbone while mountain biking.

The 'Monuments Men' star told Jay Leno that he snapped his clavicle after his bike got stuck on a bunch of rocks while he was riding down a hill and he tumbled over the handlebars.

According to the Hollywood Reporter, Damon added that he is not a very good mountain biker, and he just hit a pile of rocks, and that he kept going on even though the bike had stopped.
