Not sure if this is out there, but longtime assistant Matt Reynolds has been tabbed to coach the Celtics’ summer league team.

Luke Kornet is out and Luka Garza is in, and plenty of questions about the Celtics roster remain. But sources have stressed that a push for further reconstruction continues.

League source confirms the Celtics have signed center Luka Garza to a two-year deal.

I’m told Al Horford continues to mull potential options for next season and at the moment appears unlikely to have a final decision on the first day of free agency tomorrow.

According to a league source the Celtics are picking up JD Davison’s option for next season but it will be non-guaranteed, preserving some flexibility for both sides.

One year after winning a title, the Celtics’ roster overhaul is here. via @BostonGlobe.

Was told by a league source that the Celtics sale is a separate process but that everything remains on track for that deal to be approved and finalized.

A league source said the Celtics acquired Anfernee Simons, who is on an expiring deal, because they like what he can bring to the roster, but added that they will "remain engaged on all fronts.".
