Colchester United central defender Magnus Okuonghae has been ruled out for the rest of the season with an ankle injury.
The centre-half has been sidelined for the last three months with the injury and will now have an operation in a bid to finally solve the problem.
"Magnus is due to have his operation on Tuesday," manager John Ward told the club's official website.
"We have decided between us all that an operation is the best course of action.
"It means he will miss the remainder of the season but we will have him back for pre-season fit and well."
