Lamont Peterson lost a majority decision this past weekend against Danny Garcia. And even though the bout was contracted as a non-title, 143lb catchweight fight the IBF still took the result into consideration. After losing the decision to Garcia, the IBF stripped him of his 140lb title. It's also being reported that had Peterson won, he would've been able to hold on to that title awhile longer.
Most people will probably look fondly on this decision by the IBF as Peterson was mostly viewed as only a paper-titlist anyway. The way the sanctioning bodies function in practice, it can be difficult to ascertain what move they might make next, but they almost universally act in the best interest of politics and money. With Peterson no longer holding onto a title at 140lbs, he is mostly likely going to be headed up to the welterweight division. Meanwhile, the IBF have ordered Cesar Rene Cuenca (47-0, 2 KOs) to fightIk Yang (19-0, 14 KOs) for their now-vacant title.
