Michael Lenahan, 23, of Philadelphia, Pa. is gored in the leg by a fighting bull during a traditional bull run in Pamplona, Spain, Thursday July 12, 2007. Two American brothers were gored Thursday during the longest and bloodiest morning bull run at the San Fermin festival in the northeastern city of Pamplona. Lawrence Lenahan, 26, of Hermosa Beach, Calif. and Michael Lenahan, 23, of Philadelphia, Pa. were gored by a bull who strayed from the pack, turned around and ran the wrong way. The older brother suffered a eight-inch (20-centimeter) goring in the left buttock after a dangerous sharp right turn in the course Lenahan described as a ‘dead man’s curve.’ The younger brother was injured shortly before the bull ring, the end point of the daily runs, after the bulls horn entered beneath his skin in his right shin.
