The Toon legend took over the job as Newcastle manager last nigh, but is not interested to take over from Joe Kinnear for next season.
Shearer, 38, said: “This is for an eight-game spell, I’m looking no further than that.
“Joe Kinnear is in the job at the moment and recovering well from his operation.
“I’m here for eight games and eight games only and I’ll try to keep this team in the Premier League.”
