The midfielder left the Tottenham Hotspur Stadium in a protective boot following last weekend’s 2-0 win against Manchester United but is fit for the trip to the Vitality Stadium.
Speaking to TNT Sport before the game, Maddison said: “I have recovered well. I took a little bit of a knock but nothing major and I am good to go.”
Postecoglou said on Friday: “People would have seen him in a moon boot and thin it's more serious, but it was more precautionary.
“We've been pretty careful with him. There was no real push to have him available, we left it up to him. He has felt good and probably could have trained yesterday, but the medical team wanted to make sure he's okay. Again, it just depends how he pulls up, but obviously nothing serious.”
Tottenham are unchanged from the team that beat Manchester United last weekend.
