Manager Bruno Ribeiro has admitted that left-back Kiko is set to miss the opening game of the season against Bradford City.
With Adam Yates also injured, central defender Kjell Knops is set to deputise at left-back.
Ribeiro told the Sentinel: “Left back, we don’t have. Sometimes I have put Kjell there. I like Kjell at left back and maybe he will start at left back because we don’t have Kiko ready for Saturday.
“But I will put the best eleven next Saturday to win the game.”
