Lukas Jutkiewicz took a hefty knock in the back in the early minutes of Coventry City's 1-0 defeat at West Ham United yesterday and will be a concern for Saturday's FA Cup tie against Southampton.
Speaking to the CT about Jutkiewciz being forced off in the 69th minute, Andy Thorn said: "He took a whack in his lower back.
“We kept him on longer because we needed his height at set-pieces, but young Shaun did terrific when he went on – he gave us some fresh energy and got himself into a couple of good positions at the end.”
