All of this is in response to this offer made last Fridayon behalf of the Chavez Jr. camp by Fernando Beltran to Martinez of a 70/30 split and the fight in September. Martinez and his advisor Lewkowicz say it's B.S. and they don't believe Beltran and they would want the fight in June. Lewkowicz says Arum and Chavez Jr. are the ones who don't want the fight so they don't believe them on the offer. Lewkowicz says Martinez doesn't even care about fighting Chavez Jr. anymore and just wants the WBC to strip him and give him his belt back.
