England's Mike Brown said he is "not a robot" after he was involved in a verbal altercation with a fan following Saturday's defeat by South Africa. Full-back Brown and prop Joe Marler exchanged words with a supporter after the second Test in Bloemfontein. Brown, 32, told BBC Sport that when an England fan is "screaming obscenities and saying you're not trying, you are going to have a reaction". "I just told him to shut up basically," added the Harlequins player. "You can call me whatever in terms of how I've played, that's fine. But don't turn around and say I'm not trying when I'm coming off with bumps and bruises and aching and I've given everything I can for England."
