Paul Pierce’s jersey retirement ceremony does not look like it will serve as a reunion for the Boston Celtics’ Big 3. ESPN’s Marc J. Spears reported on Saturday that Kevin Garnett and Ray Allen are not expected to attend Pierce’s jersey retirement ceremony on Sunday. Rajon Rondo, who was the other star player on the Celtics’ championship team in 2008, will not be there either as his New Orleans Pelicans are on a road trip.
