He has been part of Flyers broadcasts since 1980, when he began working radio games part-time with Gene Hart.
Between TV and radio broadcasts, Coates has covered more than 3,000 Flyers games.
During that time he established a rapport with the fanbase that has made him one of the more popular figures in the history of the organization.
"As someone lucky enough to have spent so much time with 'Coatesy' over the years as I have, I can tell you the love affair with this team, with this fanbase, was genuine, heartfelt and mutual," said Tim Saunders, Coates' radio partner. "In the booth his energy, his sometimes off-the-wall persona made even the toughest Flyers games and seasons more fun."
The ceremony also featured classic moments from his between-periods TV feature, "Coatesy's Corner," which featured numerous Flyers players over the years demonstrating hockey skills or in funny skits.
There were more 'Coatesy's Corner' moments played during the game, as well as tribute messages from current and former players, among them Scott Laughton, Travis Konecny, Claude Giroux and Wayne Simmonds.
