Akin Famewo faces a lengthy spell on the sidelines with the injury sustained at MK Dons last Saturday.
It was a bittersweet afternoon at Stadium MK for the new recruit, who was impressing on debut for the Owls before being forced out of the action before half time.
Darren Moore has now revealed the central defender will be sidelined for ‘some considerable time’.
The manager stopped short of pinpointing a time frame but is resigned to losing Famewo for the immediate future.
He said: “Akin is going to be out for some considerable time, which we’re all gutted for him about. We wanted the fans to see him and what he’s about, but we do think he’s going to be out for some time.
“The exact length of time has not been distinguished yet, but it’s going to be some time. I don’t want to put an exact time on it because every player is different.
“I was really impressed with him at MK Dons, I really feel for him, it’s an impact muscle injury and we all want to see him back as soon as possible.”
