Liverpool loanee Harry Wilson has suffered another injury setback.
The 21-year-old scored within three minutes in Derby County's 1-1 draw with Middlesbrough on New Year's Day.
However, his afternoon was blighted by a hip injury suffered during the second half.
Despite the knock, Rams boss Frank Lampard remains hopeful that it is nothing serious.
"He has got a problem with his hip, an impingement on his hip which I think is good news, I hope, because it is not a muscle," Lampard said.
"So he will be assessed over the next couple of days and we will see if he is available for the weekend."
