The New England Patriots signed veteran tight end Nate Byham, the team announced Sunday.

Terms of the contract were not announced.

Byham, 26, is a veteran of four NFL seasons with the San Francisco 49ers (2010-11) and the Tampa Bay Buccaneers (2012-13).

The 6-foot-4, 264-pounder blocking tight end originally entered the NFL as a sixth-round draft pick by the San Francisco 49ers out of Pittsburgh in 2010. He was signed by Tampa Bay on Oct. 2, 2012 after being released by the 49ers on Aug. 16, 2012.

In his four NFL seasons, Byham has played 29 games with 11 starts, totaling 11 receptions for 83 yards and one touchdown. Last season in Tampa Bay, Byham was limited to four games and finished with three receptions for 38 yards.

Byham gives the Patriots added depth at tight end as starter Rob Gronkowski is recovering from a torn ACL. Michael Hoomanawanui is next on the depth chart, followed by D.J. Williams and undrafted rookies Justin Jones and Asa Watson.

Byham is also recovering from a torn ACL. He was placed on season-ending injured reserve last Oct. 1. He worked out for the Patriots on May 21.
