England forward Billy Vunipola says he had no idea his late try against Fiji had secured a World Cup bonus point.
Vunipola's score at the death was England's fourth try of the game which earned them an important extra point in their Pool A opening match.
Tournament hosts England opened the competition at Twickenham with a 35-11 victory over the Pacific Islanders.
"To be truthfully honest with you, I didn't know that bonus points counted in the World Cup," Vunipola said.
"I was just more excited that I'd scored a try. It's always good to get over for your country.
"I'm just happy we won and we move on to the next game."
Number eight Vunipola, 22, will be familiar with the bonus-point system from playing with his club Saracens in the Premiership.
Teams claim four points for a win and two for a draw, but can add an extra point for scoring four or more tries or by losing by fewer than eight points.
England's maximum haul of five points could prove vital as they look to be one of the two sides to progress to the quarter-finals from a group that also contains world number two Australia and world number five Wales, as well as Uruguay.
