Floyd Mayweather has no rivals in the ring, but as a promoter he and Oscar de la Hoya have been going at each other's jugulars for years now. After dispatching of Canelo Alvarez and throwing him into heap of fighters de la Hoya has thrown at him, Mayweather has the upper hand and he knows it.

On Monday, Mayweather's Instagram page tweeted out a photo that made fun of de la Hoya's ongoing rehab stint.

On Tuesday, Mayweather issued an apology and denied culpability for the tweet. Mayweather may have a brash public persona, but he's not heartless.

After the bout, Mayweather called De La Hoya a champion and wished him the best in his recovery.

“As I clearly stated during my fight week and again in the post-fight press conference, I completely support Oscar De La Hoya and his family during this difficult time in his life,” Mayweather said in the statement. “Although we have had our differences in the past, I stand by him unconditionally and would never personally disrespect him or anyone else who struggles with addiction.

“I apologize to Oscar and his family for this posting. I wish him well and am rooting for him to win his fight, too. I also apologize to all of my followers for this ridiculous post. I have no ill will towards anyone and have repeatedly stated that I only seek positivity in my life and for others.”
