The Celtics have stayed mostly mum about their delegation that met with free agent forward Kevin Durant on Saturday evening.

But a picture posted online Saturday appeared show one very special guest. In the picture, which was posted to Imgur.com, Celtics president of basketball operations Danny Ainge and team co-owner Steve Pagliuca were joined by Patriots quarterback Tom Brady.

A league source who is in the Hamptons for Durant’s meeting with the Celtics verified that Brady was there and part of the pitch to lure Durant to Boston.
