Dr. Richard Harkaway, a Philadelphia urologist who is originally from Long Island, wrote that it was Westbrook who initiated the confrontation, which ended with Harkaway being tossed from the Wells Fargo Center in Philadelphia during the 76ers’ season-opening loss. “To all my FB friends who are seeing a picture of me on the Internet giving the finger to Russell Westbrook. Actually two fingers,’’ Harkaway wrote in a private post. “Not as simple as it seems. I love to scream at the players and anyone who has been to a game with me knows this. Part of my charm. What you may not have seen on any of the video clips is what started the whole thing, which was Russell Westbrook saying ‘sit down f—ing fat boy’ when I stood up to boo.”
