Ole Gunnar Solskjaer said that Marcus Rashford could miss time with a groin injury.
"He felt his groin so probably be out for a little while. I can update you later when I know a little more. It is just one of these moments. We've had, histrionically, loads of centre-backs of the last few years struggling with injuries. At the moment it is strikers. Hopefully Mason and Anthony will be back for Arsenal and hopefully one for Rochdale," said Solskjaer following United's 2-0 loss to West Ham.
Paul Pogba, Anthony Martial, Mason Greenwood, and Luke Shaw also missed the match due to injury.
