Dan Lydiate insists Wales can cope despite their injury concerns, playing down fears over his own health.
The Welsh flanker went off late in the win over Uruguay, while Wales also lost hat-trick hero Cory Allen for the rest of the tournament.
With Rhys Webb and Leigh Halfpenny among those to pull out before the competition began, it's been a far from smooth build-up for Warren Gatland.
But Lydiate believes that Wales will take the injuries in their stride ahead of Saturday's crucial clash with England at Twickenham.
"It's hard but we've just got to focus on the task in hand and there's no better opportunity to come up here and play England in their own back yard," he said.
"We've had more injuries than we'd like but it is just the way it goes sometimes.There are boys to come in to fill those places and as a squad we're in a strong place. We've got a massive challenge this week and we've just got to focus on each day and each game as it comes.
"The World Cup is always different. We always love playing against England but the last run of games hasn't gone in our favour. We want to put that right this week.
"I was fine to come back on but there was only ten seconds left in the game. I passed my off-field test straight away to come back on so I'll just have another test now in the week. I feel fine."
