Al Horford announced what has been expected since July: he will leave Boston as a free agent and join the Golden State Warriors.

You have welcomed me and my family with open arms since I first arrived, and this chapter of my career will hold a special place in your hearts," he wrote. Raising the 18th championship flag with the city will be a moment I will cherish forever. I am eternally grateful to the Celtic fans and management."

However, Al Horford will not be able to attend the Braves' media day on Monday as his contract cannot be officially signed until after Kuminga's departure is resolved.
