The Redskins have added depth to the tight end corps with the signing of four-year NFL veteran Zach Hilton, the team announced on Monday.

The Redskins also signed first-year wide receiver Adrian Madise and released running back Kerry Carter and wide receiver Taylor Sele.

Hilton participated in the Redskins' three-day mini-camp from May 4-6. He played with the New Orleans Saints from 2003-05 and the New York Jets last season.

Hilton, listed at 6-7 and 262 pounds, originally signed with the Saints as an undrafted rookie. In 2005, he saw extensive playing time, playing in 15 games with six starts. He logged 35 catches for 396 yards and one touchdown.

Hilton joins a tight end corps that includes starter Chris Cooley and backups Todd Yoder and Eric Edwards. The Redskins also drafted Michigan tight end Tyler Ecker in the seventh round of the April 28-29 NFL Draft.

Hilton grew up in the Washington, D.C., area and attended Our Lady of Good Counsel High School in Wheaton, Md.

He played his college ball at North Carolina, where he was a two-year starter and logged 31 career receptions for 346 yards and three touchdowns.

Madise, 5-11 and 215 pounds, has had NFL stints with the Tennessee Titans, Tampa Bay Buccaneers and Denver Broncos.

He was originally selected in the fifth round of the 2003 NFL Draft by the Broncos. He played in 11 games as a rookie with the Broncos. He was released by the Broncos following the 2004 season.

Madise played his college ball at Texas Christian.

Carter, a third-year player, had signed with the Redskins in January 2006, but he suffered a serious knee ligament injury in preseason last year. With the addition of two undrafted rookie running backs to the roster last week, it was decided to release Carter.

Sele had signed with the Redskins on April 30 as an undrafted rookie. After the weekend Rookie Camp, the team decided to release him.
