Marc Guehi and Declan Rice are both doubts for England’s World Cup quarter-final against Norway on Saturday night.talkSPORT understands that Guehi has picked up a hamstring strain, while Rice has been suffering from a sickness bug.Guehi has picked up a hamstring strain and is a big doubt for EnglandGettyThe pair both missed training on Thursday and they remain doubtful for the clash which is now less than 48 hours away.Guehi has played every minute at the World Cup for the Three Lions since a 10-minute cameo in their opening win over Croatia.He has been a staple feature at centre-back, but an injury could now see him forced out of the line-up for the quarter-final. It has been reported that the defender was suffering from muscle fatigue following the hard-fought victory in Mexico.However, it appears that he suffered a hamstring strain and he now needs to overcome that ahead of Saturday’s game.As for Rice, he has already spent the majority of the tournament playing through the pain and reaching his limits.But he has actually been absent from training for two days straight due to a sickness bug and not an injury.According to the BBC, England have taken steps to stop the bug spreading and forcing more players to sit out, with the Norwegian camp also suffering from the same problem.A crucial step will be for both Rice and Guehi to train with the squad on Friday and rejoin preparations for the match.If they don’t feature, then doubts will continue to rise over their chances of starting against Norway on Saturday.Rice has been struggling for fitness at the World Cup and now he has a bugGettyWho could replace Guehi?talkSPORT’s Jason Cundy believes Dan Burn would be the perfect replacement for Guehi if he isn’t fit, given what is surely going to be a very physical battle with Erling Haaland.“It’s not good,” Cundy said on The Sports Bar. “Instantly when you said Guehi could be out and the worst case scenario is he can’t start…“100 per cent [I’m going for Dan Burn], 100 per cent. “I get the argument for Dan as whenever he plays against Haaland, the pair of them love the physicality, they enjoy that side of the game, it’s part that you don’t often see. “These two love that part of the game…and Konsa alongside him.” He added: “Going Burn is my first instinct… if I had to pick two centre halves, I’d rather see Burn next to Konsa because of the physicality, you’re not going to bring in Stones, are you?”Burn starred off the bench for England last time out – could he replace Guehi?GettySome positive news England right-back Reece James trained with the squad on Thursday, having missed the last three games due to a hamstring problem.The Chelsea captain’s availability would be a timely boost for Tuchel after Jarell Quansah’s ban was extended to two matches. talkSPORT understands Djed Spence is in pole position to start at right-back, although James is pushing to prove he can play 90 minutes.England vs Norway: talkSPORT coverage England will take on Norway on Saturday, July 11.
