Free-agent wide receiver Antonio Brown hit the boxing ring Tuesday amid rumors of a possible match against YouTube personality Logan Paul.
Streaming service DAZN, which aired Paul's last fight against fellow YouTuber KSI, shared some footage on Instagram of Brown working out at Punch Elite Fitness in Miami.
Brown also spent some time with former NFL wide receiver Chad Johnson and former heavyweight champion Evander Holyfield on Tuesday.
"I know he's a hard worker and I know he's good," Holyfield said in a video posted to Brown's Instagram account.
Brown confirmed his interest in a fight against Paul in a recent interview with Complex's Zach Frydenlund, saying he plans to train with Floyd Mayweather Jr. in Las Vegas.
