Daley Blind is expected to feature in Ajax's matchday squad against Utrecht on Sunday, after being diagnosed with a heart condition which has kept him out of action for the last two months.
Blind was medically examined after suffering from dizziness during a Champions League defeat to Valencia on December 10.
The 29-year-old was subsequently diagnosed with heart muscle inflammation, also known as cardiomyopathy, and has not played for Ajax since.
