The veteran defender could make today's matchday squad for the derby at Manchester City.
Asked about Evans' availability on Friday, Amorim said: "Yeah, he's training already."
On his first Manchester derby, Amorim also said: "Yeah, I'm really focused on the details. I just want to improve the team so I cannot live it like a normal derby, like it should be – two great teams fighting for the title. And it's not that in this moment.
"So it's just one more game with a very good opponent. Both teams are struggling in the moment, so I hope, in the future, I feel that real feeling of a derby. But I know that it's really important for our fans. But my goal now is to improve the team, win games and I will try to win this game."
