LAS VEGAS — Promoter Bob Arum has delivered what he says will be his last proposal to salvage the fight between Manny Pacquiao and Floyd Mayweather Jr. The fight is in jeopardy because of a blood testing dispute.

Under Arum’s proposal, the Nevada Athletic Commission would have the final say in how much testing there would be for the fight and when it would take place. Preparations for the fight would go forward and there would be three blood tests — none within 30 days of the fight — unless the commission decided otherwise at a mid-January meeting.
Arum said Sunday that Pacquiao’s side would go no further than the proposal, and that he will begin negotiations Monday with Paul Malignaggi for the March 13 date the megafight was supposed to take place on.
