The midfielder shared an update on his recovery via social media on Monday evening, prior to Scotland's clash with Denmark, and it's positive news for Manchester United.
Club football resumes this weekend as United travel to Watford in a Saturday Premier League fixture. With several injuries to key players already, the absence of McTominay would be a blow to Ole Gunnar Solskjaer's squad.
On Monday, the 25-year-old said: "Tough one to take not being available to help the boys this past week through not being well but I’ve recovered well and just want to wish the squad the best of luck for tonight.
