Coventry defender Ben Turner is set to miss the first four weeks of pre-season training after twisting his ankle. Turner picked up the injury while carrying out his own fitness regime ahead of joining the rest of the squad.
Boss Iain Dowie told the club website: "Ben was obviously keen to be as fit as he could for pre-season."
Turner, 18, made his full debut in the Sky Blues' penultimate league game against West Brom and signed a new two-year contract last month.
