Jamaal Lascelles says there's "no panic" after Newcastle United lost two defenders to injuries.
Florian Lejeune and Paul Dummett were forced off in last weekend's season-opener against Tottenham Hotspur.
Centre-half Lejeune suffered ankle ligament damage under a challenge from Harry Kane at St James's Park, while left-back Dummett limped off with a hamstring problem.
Newcastle say the pair will be out "for weeks, rather than months".
Lascelles – who had a knee injury himself in pre-season – came off the bench and replaced Dummett last Sunday.
And United's captain, preparing for Sunday's game Premier League against Huddersfield Town at the John Smith's Stadium – feels manager Rafa Benitez has enough strength in depth at the club.
“It's never nice to get injuries that early on, but we've got a big squad in depth with quality all round, so there's no panic," said the 23-year-old, who led the club to the Championship title last season.
“We'll try to get them back as soon as possible, but we have just got to focus on the team that we have and what the starting line-up is going to be for Huddersfield."
Lascelles started the season on the bench after missing a number of pre-season games through injury.
However, the England Under-21 international was quickly pressed into action.
“I don't think my injury helped in pre-season, because I didn't really play any pre-season games, but like I said before, in every single position we have got a lot of competition," said Lascelles
“We just need to make sure that individually and collectively, we are all at it because your place will be taken. You have got players waiting to fill in."
Lascelles and his team-mates took part in an open training session at St James's Park today.
More than 12,000 fans watched Benitez and his coaches put the players through a series of drills and a practice game.
“It's massive," said Lascelles. "I can't thank them (the fans) enough, because as players it does mean a lot when you travel down to London (and) you have got a massive following and sell outs everywhere.
“It means the world the fans. I get disappointed when we can't perform on the pitch, because I feel like we're not giving them anything back.”
