Playing career

New York Giants

Campbell was selected by the New York Giants in the third round (79th overall) of the 1999 NFL Draft. In 2000, he became the team's starting tight end and was mainly used as a blocker. He was a part of the Super Bowl XXXV team.

Dallas Cowboys

Campbell was one of the first free agents to sign with the Dallas Cowboys after Bill Parcells was named the head coach in 2003. He quickly became a team leader and although Jason Witten emerged as the main tight end, he still served as a mentor and remained a key blocker on the offensive line.

In 2004, he only played in three games because of torn ligaments in his foot and was placed on the injured reserve list on September 30. The next year he recovered from appendectomy surgery (July 27), missing only 10 days of practice and returned to start all four preseason games. The team employed two-tight end sets, which allowed him to start 12 games.

Detroit Lions

On March 14, 2006, he was signed as a free agent by the Detroit Lions. Known mostly as a blocking tight end, he posted career-highs in receiving yards (308), average per reception (14.7 avg), long reception (30 yards) and touchdowns (4) (the most by a Lions tight end since 2001).

On September 22, 2007, he was placed on the injured reserve list with an elbow injury. On September 9, 2008, he was again placed on the injured reserve list with a hamstring injury. He was released on February 9, 2009.

New Orleans Saints

On February 26, 2009, he signed as a free agent with the New Orleans Saints reuniting with head coach Sean Payton who was his offensive coordinator with the Cowboys. On August 10, he was placed on the injured reserve list with an MCL injury he suffered in training camp. He was still able to receive his first Super Bowl ring and retired at the end of the year.

Coaching career

Campbell was the tight ends coach with the Miami Dolphins until he took over as the interim head coach when Joe Philbin was fired on October 5, 2015. Owner Stephen M. Ross stated "The grit that Dan possesses will do wonders in that locker room."

After being let go by the Dolphins in January 2016, Campbell was hired by the Saints as the assistant head coach and tight ends coach.
