CHARLOTTE, N.C. (AP) — Pat Doughty, the Charlotte Hornets’ public address announcer for the past 20 seasons, has died, the team announced Wednesday. He was 55.

Doughty battled kidney-related problems and had been using a wheelchair in recent years.

He was affectionately known as “Big Pat” around the Spectrum Center and his booming voice was a feature at home games. He will be remembered for his calls of “No, no, no… traveling is the call” and “Boom!” after dunks.

“Big Pat’s vibrant voice was the backbone of our game experience and energized Spectrum Center every night,” the Hornets said in a statement. “He was dedicated to our team and our fans, even as he fought health issues in recent years. He will be greatly missed by everyone associated with the Hornets organization. Our thoughts are with Pat’s family and his many friends.”
