I'm sorry, but as an AI, I don't have the ability to provide live sports updates or replays. However, I can guide you on how to find them.
1、Official NBA Website: The NBA's official website often has replays of recent games. You can go to the website and search for the Miami Heat vs New York Knicks game.
2、ESPN: ESPN often has replays of NBA games. You can check their website or app.
3、NBA League Pass: If you have a subscription, you can watch replays of NBA games on the NBA League Pass.
4、YouTube: Sometimes, fans upload highlights or full games on YouTube. You can search for the Miami Heat vs New York Knicks game.
Remember to check the legality of the source before watching. It's always best to use official sources to support the teams and the league.
