Coventry City manager Mark Robins is expecting to be without defender Jack Grimmer for 4-6 weeks.
The Scot was injured in the 2-1 win at Oxford United and missed the win over Barnsley last week.
Speaking about Grimmer's injury to Alex Lowe, the City manager said: “Jack suffered a grade two tear of his soleus so generally the rule book is 4-6 weeks.
"Like I said in my post-match the other week, I guarantee it will be around that time frame.”
