The 26-year-old Byham spent the past two seasons with Tampa Bay after his first two seasons with San Francisco. Byham has 11 catches for 83 yards and one touchdown in 29 games since the 49ers drafted him out of Pittsburgh in the sixth round in 2010. Last season, he had three catches for 38 yards in four games with the Buccaneers.
The Patriots have been seeking depth at tight end going into training camp that begins Wednesday. Rob Gronkowski was a limited participant in minicamp last month as he continued his comeback from a season-ending knee injury last year.
