(Reuters) - Fans who taunt Bryson DeChambeau with "Brooksie" chants to show what side they have taken in his well-documented feud with Brooks Koepka could be thrown out of tournaments, PGA Tour Commissioner Jay Monahan said on Tuesday.

Monahan, speaking to reporters ahead of this week's season-ending Tour Championship in Atlanta, said disruptive behaviour that goes against the civility and respect that are hallmarks of the game will no longer be tolerated.
