Floyd Mayweather has offered to cover the funeral costs for George Floyd, whose death while in police custody has led to days of protests across the United States and beyond.

Mr Floyd died last Monday after a white police officer held him down by pressing a knee into his neck and sports stars have joined in the widespread condemnation.

Mayweather Promotions confirmed that the former five-division world champion had reached out to Mr Floyd's family with an offer to cover all costs relating to the funeral.

Tiger Woods added his voice on Tuesday morning. In a post on social media, the 15-time major winner wrote: "My heart goes out to George Floyd, his loved ones and all of us who are hurting right now. I have always had the utmost respect for our law enforcement.

"They train so diligently to understand how, when and where to use force. This shocking tragedy clearly crossed that line. I remember the LA riots and learned that education is the best path forward.

"We can make our points without burning the very neighborhoods that we live in. I hope that through constructive, honest conversations we can build a safer, unified society."
