Earlier this week, Floyd Mayweather posted a photo of him and his 15-year-old son Koraun on Instagram. The photo featured father and son riding around in a brand-new gold Bentley golf cart that Mayweather just bought the boy for his birthday. But in a new report that was just published by USA TODAY Sports, Koraun and his mother Josie Harris talk at length about an incident that took place back on September 9, 2010 that involved Mayweather kicking and punching Harris—and it's pretty clear that Koraun is still upset with his dad after what happened that night.

The incident in question has been pretty well documented in the past. Back in May 2013, Yahoo! Sports spoke with Harris about what took place that night. She said that Mayweather attacked her in front of her children and that he left bumps and bruises all over her body after questioning her about her relationship with NBA player C.J. Watson.

But in the new USA TODAY Sports report, Koraun—who was 11 at the time of the incident—also speaks about what happened on that night. He was the one who ran to get help after seeing what was transpiring between his mom and dad. And he's the one who still sounds like he's coming to terms with what his dad did.

"He is a coward," Koraun says at one point in the interview.

Mayweather refused to speak with USA TODAY Sports to give his side of the story. But the report is still worth a read, especially in light of how dismissive Mayweather was with regards to domestic violence during an interview with Rachel Nichols back in September. You can also watch Harris talk to USA TODAY Sports about Mayweather in the clip below. At one point, she admits that she "was a battered woman" and talks about why it took her so long to come to that conclusion.
