Hear from Gordon Hayward, Brad Stevens and Danny Ainge after the free agent's signing with the Boston Celtics became official Friday afternoon. Boston's Summer League team continued rolling in the Vegas Summer League. The Celtics will lose long-time strength and conditioning coach Bryan Doo this season.

The Boston Celtics will be holding a press conference today at 1:30 p.m. to make a "major team announcement."

As always, CLNS has you covered.

Mike Petraglia will be covering the event live. You can follow along with Mike on Twitter @Trags.

Also, stay tuned to the CLNS YouTube channel for up-to-the-minute videos and postings.

The Celtics have scheduled a presser for Friday at 1:30 p.m. Eastern. Thought Gordon Hayward is unlikely to be present and many beat writers are still in Las Vegas for Summer League, Danny Ainge may be officially announcing the Gordon Hayward signing. CLNS Media will be present and bringing you on-the-spot audio/visual coverage.
