Miami Heat guard Gerald Green has been released from hospital after a four-day stay, according to a report.

The 29-year-old was admitted last week for an undisclosed illness before his side's match against Atlanta Hawks, although the team confirmed that he was safe and healthy the following day.

However, Green was kept in hospital for a further three days before he was released, with no reason emerging for his prolonged stay, reports WPLG in Miami.

Green had averaged 10.3 points per game in his first three matches of the 2015-16 season.
