Brown could miss remainder of Rams season
Derby County forward Dajaune Brown could miss the rest of the season as he needs hamstring surgery.
The 19-year-old academy graduate has made 15 Championship appearances for the Rams this season, although his only three starts, and his lone league goal came before Christmas.
He is one of several injury headaches for head coach Paul Warne ahead of Sheffield United's trip to Pride Park on Saturday (15:00 GMT).
Warne told BBC Radio Derby: "Daj has to have an operation on his hamstring so he's going to be out for a long period.
"Corey Blackett-Taylor (hamstring) is out for a lengthy period - we won't see him for a long period."
Full-back Kane Wilson is also set to miss his second game with a hamstring strain sustained against Sunderland while Warne reported "Callum Elder has tweaked his groin so we won't be missing him too long - days or weeks, definitely not months."
New arrival Matt Clarke, who signed this week from Middlesbrough, is in contention to start in defence but while Nat Phillips (calf) has started running, he won't be back in full training until next week.
