"You guys got one of the best athletes, and one of the best basketball players in the world," Mayweather said on "The Waddle & Silvy Show." "Derrick Rose is truly amazing. He's a great athlete. I keep my fingers crossed and hope he can bounce back from this (ACL) injury."
Mayweather said there was a time he would communicate frequently with Rose.
"We haven't spoke in a while, but we used to speak almost every day," he said. "At one particular time when he got to the playoffs, we would speak every day."
