Evans, 32, was the No. 1 free agent receiver on our board heading into free agency. He'll now be joining a 49ers team that finished 12-5 last year and made it to the Divisional Round of the NFL Playoffs.
The two-time All-Pro and future Hall of Famer, who posted an NFL record 11 straight 1,000-yard seasons to start his career, had his first bad injury this past season - breaking a collarbone that forced him to miss 10 games.
He still managed 368 receiving yards with three touchdowns on 30 receptions in the games he did play in.
The Tampa Bay Bucs released a statement regarding Evans, who had been with the team his entire career.
