Arsenal striker Eduardo has undergone "simple revision surgery" on the left ankle he dislocated over a year ago.
The Croatia international has returned to action since the sickening injury but has now had a minor operation.
"Eduardo underwent simple revision surgery on his left ankle," read a statement from the club.
"The operation went well and Eduardo will follow a dedicated rehabilitation programme throughout June.
He is expected to return to full training in pre-season with the rest of the squad."
