United wanted to check but have now agreed to the surgery.
‘Following consultation between Marcus, the manager [Ole Gunnar Solskjaer], club medical staff, and specialists, Marcus will undergo surgery imminently to resolve his shoulder injury,’ said United in a statement released on Friday.
‘He will now focus on his rehabilitation in order to return as soon as possible.’
Rashford scored 11 goals in 37 Premier League appearances last season as United finish second behind Manchester City.
He helped Solskjaer’s side reached the Europa League final where they lost to Spanish side Villarreal on penalties.
He made five appearances for England at Euro 2020 but was only on the pitch for a total of 84 minutes and then missed a penalty in the shootout as Italy beat Gareth Southgate’s side on penalties in the final.
