Juan Cuadrado has gone under the knife in Finland to resolve a long-term Achilles tendon issue and is expected to be out for three months.
The Colombia international had been struggling with the recurring inflammation of the Achilles tendon in his left leg, which prevented him from playing or even training regularly.
He confirmed in an Instagram post yesterday that while he had tried to avoid the surgical procedure, doctors warned him it had become necessary.
Cuadrado had the operation in Turku, Finland, performed by specialist Professor Lasse Lempainen today.
He will begin the rehabilitation process, but initial reports suggest an absence from the pitch of around three months.
This could force the club back onto the transfer market in January to find a suitable replacement on the right side of their five-man midfield.
It is particularly concerning right now, as Denzel Dumfries is also injured in that role.
The 35-year-old joined Inter as a free agent from Juventus over the summer and has made nine appearances between Serie A and the Champions League, contributing two assists.
