The striker, who missed a large chunk of last season with a hip problem, suffered a groin injury in the 2-0 defeat at Arsenal.
"I had to come off because I did something to my groin, which doesn't look good," Ameobi told the Evening Chronicle.
"I want to get back in the team and start playing as a regular.
"Injuries keeping me out isn't good for me, but this is the luck we are having at the moment. It makes it more frustrating that I had almost a season out last year and that I am struggling to get into the team.
"That's frustrating. I know what it is like to miss three or four games and then come back in is very difficult.
"I have always said that I need to play this season. I now have to get back, get fully fit and show what I can do.
"I will see how it goes in the next 48 hours. Maybe I will get some good news if it turns out it isn't as bad."
