Chris Hughton: "Nile's injured. He came off with 20 minutes to go in a reserve game with his ankle.
"He's definitely out. It's one we're assessing but it's a sore one. It's not long-term though.
"He certainly won't be available for Plymouth and at this moment it looks like he might not be available for Saturday either.
"He's just twisted his ankle. It's not a bad one, but it will take a little while to settle down."
