Watford defender Jay DeMerit fears a lengthy spell on the sidelines after a freak eye accident.
DeMerit cut his eye as he tried to take out a contact lens and the eye has now become infected.
The United States international is set to see a specialist over the injury as he can not see out of the eye.
"It was a freak thing," DeMerit told the Daily Mail. "It got worse and worse and I still can't see out of that eye.
"Scar tissue is starting to develop, which is blurring my vision, so I'm seeing a specialist and I might have to have surgery."
