British boxer Tyson Fury has resorted to homophobic behaviour in his spat with boxing legend Lennox Lewis and current world heavyweight champion Wladimir Klitschko.

Fury, 25, tweeted that they were both “homosexuals” and “100% homosexuals” – although neither boxer is known to be gay.

He peppered his tweets with a series of expletives – the homophobic ones have now been deleted.

Lewis, 48, is currently retired from the sport, and said that in spite of being nearly twice the younger fighter’s age he would still knock Fury out.

It was those remarks which lead to the latest spat with Fury.

Lewis, a former undisputed world heavyweight champion dismissed rumours early in his career that he was gay.

Earlier this week, Orlando Cruz, boxing’s first openly gay professional fighter, said his initial fears about being shunned by the boxing community following his decision to come out were unfounded.

The 32-year-old Puerto Rican went public about his sexuality in October 2012 and became boxing’s first openly gay professional fighter in the process.
