England battled at times but took advantage of a weird second-half try to overcome Japan 34-12 at the Stade de Nice and gain a bonus point in an underwhelming performance that keeps them in charge of their Rugby World Cup Pool D. With the score 13-12, England captain Courtney Lawes cantered in for a try while the Japanese players paused and waited, expecting to hear the referee's whistle for a knock-on as the ball deflected off prop Joe Marler's head.
