The iconic former manager, 84, was at the stadium for the highly anticipated fixture when he experienced a health scare.
Ferguson, who guided the Red Devils to 13 Premier League titles, remains a fixture at home games, regularly watching from the directors’ box.
He served as a club ambassador for 12 years following his retirement in 2013, a role that concluded last year under the new ownership of Sir Jim Ratcliffe.
Reports indicate that Ferguson was initially attended to by medics in the Stretford End tunnel before being escorted to a waiting ambulance.
After being assessed inside the vehicle, it is understood he was then transported to a hospital for further evaluation.
A source told SunSport that Ferguson was conscious and “okay” while in the ambulance before departing the grounds.
This incident follows a more serious health crisis in May 2018, when Ferguson suffered a brain haemorrhage and required emergency surgery.
The club is currently awaiting confirmation regarding his health situation, as the details of his condition are not yet known.
