Fighters usually enter a ring with little more than their trunks, gloves and the survival instincts gleaned from years of training in a gym.
Not so with Marvin Jones, who also came prepared with a cell phone — which promptly fell out of of his waistband during a light heavyweight fight against Ramon Luis Nicolas at the Turner Agri Center in Arcadia, Florida last weekend.
Watch the head-shaking moment below as the referee has to stop the fight during the first round to retrieve the gadget which fell out of his trunks onto the canvas.
Jones would have been better off packing horseshoes in his gloves. Nicolas won by a first-round knockout.
Now where's that selfie of Jones laid out on his back?
