Paraguay and Japan were 0-0 at full time and now head to extra time as both teams try to advance to the World Cup quarterfinals for the first time.
Paraguay dominated possession, but Japan had the better chances. Midfielder Daisuke Matsui intercepted a poor clearance from the Paraguay defense and his shot from 25 meters (yards) hit the crossbar in the 22nd minute.
Paraguay forward Lucas Barrios latched onto a through ball in the 20th and sidestepped the last defender into the penalty area, but his weak shot went straight at Japan goalkeeper Eiji Kawashima. The best second-half chance fell to Paraguay's Edgar Benitez.
The winner of the match will face either Spain or Portugal in the quarterfinals.
