West Ham defender Arthur Masuaku has been hit by a six-week injury.
The 22-year-old Frenchman was brought in for £6million from Olympiacos in August as cover for injured left-back Aaron Cresswell.
But Masuaku has now joined Cresswell on the injury list after damaging knee ligaments during the EFL Cup win over Accrington on Wednesday night.
For manager Slaven Bilic it is another problem to solve in a defence which conceded eight goals in their previous two Premier League outings.
"Masuaku did his knee against Accrington, he damaged ligaments and we will know better in a week but it's going to be at least six weeks, if not more," said Bilic.
"Some players can play in different positions, and you can fill gaps, but when you have two left-backs who have done the same ligaments it's not good news.
"But I'm not looking for excuses. But we have a good team and I expect us to do it on Sunday."
"It was in the papers on the day we played Accrington that Carroll had had a setback, but it's not true," he added.
"We are expecting him and Cresswell to join and train with the team after the international break.
"Injury-wise we look much better than at the beginning of the season. We have a good team and I expect us to be really good in every way on Sunday afternoon."
