Swansea's Dyer ruled out for two months
The winger requires surgery on an injured ankle and has "extra bone growth" in the joint.
Dyer said: "I saw a specialist last week and the MRI scan revealed the extra bone growth at the back of my ankle. There is not a lot I can do about it".
The Swansea man spent last season on loan at Leicester where he won the Premier League title with the Foxes.
