Barnsley defender Ben Williams is likely to miss most of the 2020/21 season after picking up a serious knee injury at St George's Park this week.
The 21-year-old left-back is now expected to miss at least seven months.
Head coach Gerhard Struber said: "It makes me very sad. Ben Williams has an ACL rupture. It has a big impact on the team. It will be seven to nine months so he will miss a lot of the season."
