The midfielder featured in the first two games of the season but will sit out games for the near future for the Red Devils.
Scot McTominay is set for a spell on the sidelines for an unspecified duration after undergoing groin surgery.
McTominay was a notable omission from Scotland manager Steve Clarke’s squad for next month’s 2022 World Cup qualifiers.
Aberdeen midfielder Lewis Ferguson filled the void left by the Manchester United man, earning his first senior call-up for the games against Denmark, Austria, and Moldova.
It has now been revealed that the 24-year-old had to go under the knife for a groin problem that was causing him “significant pain when playing.”
“Scott has undergone surgery for an ongoing groin injury that was causing significant pain when playing,” the official statement on the Man United website reads.
“Having tried all other treatment options in pre-season, surgery was deemed necessary to resolve the issue. We hope to have him back soon.”
McTominay said on Instagram: “Just to let you all know I’ve had minor surgery on an issue which has needed managing for the last couple of months.
“I hate missing games so to be missing Wolves on the weekend and the international break is so disappointing but that’s part and parcel of the game.
“Wishing all the boys the best of luck and I will be back sooner than you think.”
