Tyson Fury could reportedly face disciplinary action from the British Boxing Board of Control for an expletive rant on Twitter.
The 25-year-old took to the social networking site to criticise fellow British boxer David Haye, who postponed the pair's bout until February after suffering a cut above his eye during sparring a few days before the originally-scheduled fight.

BBBofC general secretary Robert Smith told BBC Sport: "We're not very happy about it. We'll deal with it in our normal way."
Fury was fined £3,000 in March for writing homophobic messages on Twitter.
