Pre-draft Prior to the 2012 NFL draft, Campbell ran a 4.51 40-yard dash and posted a 38-inch vertical leap at Cal's Pro Day.
Carolina Panthers On April 28, Campbell was selected by the Carolina Panthers in the seventh round (216th overall) of the
2012 NFL draft. He was the Panthers' seventh and final selection of the draft and joined cornerback
Josh Norman as one of two defensive backs selected by the team. Campbell agreed to terms on a four-year contract with the Panthers on May 10, 2012. As a rookie, he was inactive for the first 11 regular season contests of the year, but ended up starting four of the final five games at strong safety due to an injury to
Charles Godfrey. The Panthers won each of his starts, ending the season on a four-game winning streak as Campbell finished his rookie campaign with 12 tackled and a pass defensed. In 2013, Campbell lost a competition for the Panthers' starting strong safety job to
Mike Mitchell during the preseason and eventually landed on injured reserve with a leg injury. He was waived with an injury settlement on September 9, making him a free agent. On November 11, he was promoted to the active roster to replace waived safety
Jordan Kovacs prior to the Dolphins'
Monday Night Football meeting with the
Tampa Bay Buccaneers.
San Francisco 49ers Campbell signed a one-year contract with the
San Francisco 49ers on January 7, 2014. The 49ers waived Campbell on August 25, 2014.
Arizona Cardinals On February 4, 2015, Campbell was signed by the
Arizona Cardinals. On August 11, 2015, he was released by the Cardinals. ==Personal life==
