5. Ewald Lienen
OK, so who brought a shank out onto the pitch? Actually, for German footballer Ewald Lienen, it was the cleats of Norbert Siegmann—a defender on the opposing team—that did this kind of damage. A sliding tackle was all it took to open this 10-inch wound which required 23 stitches. Despite the gruesome look of things, Lienen was back on the pitch a few weeks later. So, soccer players actually used to be tough...what happened?
