The New England Patriots signed three tight ends and released three other players Sunday.

Tight ends Ben Hartsock, who has played 10 seasons in the NFL with the Indianapolis Colts, Tennessee Titans, Atlanta Falcons, New York Jets and Carolina Panthers, and Steve Maneri, who spent 2010 on the Patriots practice squad, joined the team Sunday.

Also signing Sunday was rookie free agent tight end Terrence Miller, who was released by the Jets on June 19.

Hartsock, 34, played 13 games for the Panthers last season, but did not have a reception. Maneri, 26, spent part of the 2014 offseason with the Tampa Bay Buccaneers.

He has played in 23 NFL games, including 10 starts, and has six receptions for 52 yards. The 6-foot-7, 280-pound Maneri began his NFL career as an offensive lineman. He was a tight end in college at Houston.

Also Sunday, the Patriots announced the release of three rookie free agents: running back Stephen Houston, tight end Justin Jones and tight end Asa Watson.

 Former Patriots safety Steve Gregory announced his retirement Saturday. Gregory signed with the Kansas City Chiefs in the offseason. He played 23 games in two seasons with New England, including 11 starts.
