Sherman confirmed the news himself on “The Richard Sherman Podcast.”
“I’m going to go play for the Tampa Bay Buccaneers,” he said. “I went with the best offer I had, the best opportunity to go out there and put some great tape on, to lead another group. I feel comfortable and confident in my abilities to execute and help that team win.”
The news comes after the team’s 34-24 loss to the Los Angeles Rams on Sunday.
Sherman, a five-time Pro Bowl cornerback, had left the San Francisco 49ers in March as an unrestricted free agent.
