Coventry City will be without Cyrus Christie for a month.
The defender rolled his ankle during the 1-0 win at Stevenage last Saturday and was forced off.
City manager Steven Pressley told the Coventry Telegraph: “It’s a big blow because Cyrus is such an important player for us.
“At one stage, we were thinking that he would be out a lot longer so I am relieved that we’re looking at about four weeks.”
Jordan Willis who has overcome the knock he picked up during Tuesday night's JPT exit at Leyton Orient and Arron Phillips are vying to replace him.
