The Cardinals can continue to negotiate a long-term deal with the 6-foot-8, 300-pound player through July 16. If another team signs him to an offer sheet, Arizona has the right to match it or receive two first-round draft picks as compensation.
If the franchise tag remains in effect, Campbell receives a one-year tender at a salary that is the average of the five highest-paid players at his position.
Campbell, a second-round pick out of Miami in 2008, set career bests with 72 tackles, 53 solos, and a team-leading eight sacks last season. He had an interception and forced two fumbles, recovering one.
