The Welshman sustained fractures to the tibia and fibula in his right leg in Saturday’s win at Stoke.
“During yesterday’s match against Stoke City, Aaron Ramsey sustained fractures to the tibia and fibula in his right leg. Yesterday evening he underwent surgery,” read an official club statement.
“The operation successfully reduced the fractures and whilst it is too soon to state an exact timescale for recovery, Aaron will certainly miss the remainder of this season.
“Our thoughts are with Aaron at this time and everyone at the club wishes him all the best in making as speedy a return to action as possible.”
