The goalkeeper was taken off with concussion after Shola Ameobi kicked him in the face as West Brom scored on Saturday.
Harper was given the all-clear by hospital staff, and is now back in training ahead of Saturday night's Championship home game against Reading.
Chris Hughton: "Steve Harper will start against Reading.
"Steve is very much our No 1 goalkeeper, but we're fortunate to have two very good young keepers in Tim Krul and Fraser Forster behind him."
But Harper knows full well Tim Krul is waiting for his chance ... and ready for the moment.
