TORONTO — Raptors star guard Kyle Lowry is headed to the Miami Heat. Lowry put out a social media post to his more than 907,000 Twitter followers saying "Miami Heat X Kyle Lowry" and "Let's Goo!!" followed by five fire emojis. The post came less than 45 minutes after free agency officially kicked off Monday at 6 p.m. ET. Deals will not be considered official until noon Friday, with the Raptors saying they would have nothing to say until then. Citing a source, The Associated Press reported Lowry had agreed to a three-year deal worth an estimated US$90 million in a sign-and-trade with Toronto that will send veteran point guard Goran Dragic and power forward Precious Achiuwa to the Raptors. There was no immediate word whether those players will stick in Toronto or head elsewhere in another thread to the deal.
