Simon Moore has wished fellow goalkeeper Jamal Blackman all the best following Tuesday's injury.
Loanee Blackman was injured as United conceded early - the only goal of a frustrating night at Loftus Road as the Blades suffered defeat.
Moore replaced Blackman in the game and afterwards said: "It is never nice to see players get injured. Jamal has done fantastically well, he's a great goalkeeper and has a bright future ahead of him.
"Personally, it has been frustrating to sit on the bench but myself, Jamal and Jake (Eastwood) have a fantastic rapport with Darren Ward, we all get on really well.
"I hope Jamal's OK and back as soon as possible."
