Manchester City goalkeeper Claudio Bravo may be set for a spell on the sidelines after picking up an injury in the 0-0 derby draw with United.
The Chile international suffered a calf injury in the second half as he collected a corner and was taken off on a stretcher after receiving treatment.
And the 34-year-old could miss some key matches over the next few weeks as City battle for a place in the top four.
Asked about the Bravo injury after the match, City manager Pep Guardiola said: "I haven't spoken to the doctor but it looks like the calf. We will know more on Friday.
"He has an injury and it looks like it could be a few games, but we will have to see.
"I don't know if he will be available again this season."
Former Barcelona man Bravo has endured a tough first season at City and has lost his place at times to Willy Caballero, who came off the bench to replace him on Thursday night.
Fourth-placed City, a point and a place above United, travel to relegation-threatened Middlesbrough on Sunday.
