Melton’s agent also confirmed the deal, although no financial terms were disclosed.
Melton, 28, spent last season with the Dallas Cowboys, playing in all 16 games, recording 15 total tackles and finishing second on the team with five sacks. He also had two fumble recoveries.
Dallas declined a three-year, $24 million club option on Melton last month after Melton signed a $27.5 million deal the previous year.
Melton played four seasons under Buccaneers head coach Lovie Smith when he was the Chicago Bears. He made the Pro Bowl in 2012 after recording six sacks and 44 tackles.
