LONDON (Reuters) - Floyd Mayweather sent a message to mixed martial arts champion Conor McGregor on Tuesday to stop 'barking' and find some 'bite' after months of talk about a crossover fight between the two.
Speaking after announcing an IBF world super-featherweight title bout in London on May 20 between his defending protege Gervonta Davis and Britain's Liam Walsh, Mayweather suggested McGregor was all talk.
