Winger has undergone surgery to repair broken metatarsal
Kaid Mohamed has been ruled out for three months.
The winger suffered a broken metatarsal during the 1-1 draw with Southend United last Saturday and underwent surgery this week.
“It is obviously a blow to us and for Kaid,” said manager Chris Wilder.
“He will be missing until early April and that is a real shame.
“He had surgery to repair the break this week and the focus now is getting him back firing for the final few weeks of the season.”
