In September 2013, he became the subject of controversy for unsportsmanlike behavior when video emerged of Campbell's egregious off-the-ball dive against USA's Matt Besler in a World Cup Qualifying match, earning Besler a yellow card and subsequent suspension. The spread of the footage has generated extensive discussion regarding the quality of CONCACAF refereeing, and whether such cheating should be eligible for post-match disciplinary action. Campbell faced universal condemnation, with the dive being called "pathetic", "cynical" and "disgraceful". On 13 September, the Costa Rican media reported FIFA were investigating Campbell over the incident although nothing came of that.  On 4 October, FIFA officially reprimanded Campbell for unsporting behavior.
