Coventry City have Ben Turner back running but Jordan Clarke is struggling.
Turner has been out since last November whilst Clake has missed pre-season after injuring his knee during the teams training in Portugal.
Speaking to the CT, Andy Thorn said: "Ben Turner is coming along well - he is running but has not been able to do any of the sharp football stuff yet because we don't want to take any chances.
"He's come so far now that we want to get him absolutely right even if that takes a few extra days.
"Jordan Clarke is struggling with his knee so it will be little while for him."
