Oscar De La Hoya used the Twitter social-networking site Friday to ask Bob Arum and to forgive him for implying recently that Pacquiao's success in boxing may have been due to the use of performing-enhancing drugs.
De La Hoya, whose company,, has been feuding with Arum's Top Rank Inc., sent the five-part "tweet" from the Southern California rehabilitation center where he is receiving treatment for undisclosed reasons.
"Dear Bob Arum, first I would like to humbly apologize for any pain I have caused you and your family," the 10-time world champion said in his first message.
"I also want to apologize to Manny Pacquiao for any wrongdoing on my part. You are a great champion," he added.
He also called for an end to the promotional war that has been raging between his company and Arum.
"With great humility I ask we work together for the good of the sport we dearly love. It's not fair to the fans and to the fighters," he said.
Arum and De La Hoya — a former Top Rank fighter himself — have battled bitterly over the promotional rights to Pacquiao and (both Top Rank fighters), among other issues.
Arum offered a lukewarm response to the apology when told about it.
"First I'm hearing about it," he told Steve Kim of Maxboxing. "If he's apologized, I appreciated it, but I don't know anything about it."
