By TIM REYNOLDS AP Basketball WriterMIAMI (AP) — The Miami Heat and forward Nikola Jovic have agreed on the framework of a four-year, $62.4 million extension, a person with knowledge of the talks said Wednesday night. The person spoke on condition of anonymity to The Associated Press because the contract has not been signed. It’s a significant commitment by the Heat to Jovic, who averaged 5.5 points as a rookie, 7.7 points in his second season and then 10.7 points last season. Jovic is coming off a strong summer working with the Serbian national team, and the Heat expect that his role is going to continue to grow this season. I’ve seen growth from him over three years because of that standard that they’ve had in that program.”The Heat and Jovic had until Oct. 20 to work out an extension.
