Liverpool playmaker Philippe Coutinho is expected to miss around six weeks after undergoing surgery on his injured shoulder.
The Brazilian landed awkwardly in Monday night's 2-2 draw with Swansea City and was set to have an operation on Thursday to fix the issue before spending some time in the medical room.
"He's only just having it today so the timescale from the medics is obviously up to six weeks," he said.
"We wouldn't anticipate any sooner than that. It's unfortunate for him because he's been in great form since he came here in January.
"Hopefully we'll get him back sooner rather than later and then he can come into the group again.
"These things happen in football. Hopefully he'll recover quickly and come back to us in good shape."
