The New Orleans Saints safety - who won the Super Bowl with the Saints in 2010 and with the Philadelphia Eagles in 2018 - has taken a minority stake in the Clarets following the ALK Capital takeover.
Speaking to the official Burnley website, Jenkins said: "I'm excited to enter this new relationship. Burnley is known for its tenacity, work ethic, good sportsmanship and efficient operational infrastructure.
"It is a great fit for me personally and my company to invest in the growth of the sport alongside a historic organisation that aligns with our values."
Chairman Alan Pace added: "Malcolm has a wealth of high-level experience, not only as an elite sportsman, but through his successful business and philanthropic enterprises. We look forward to him helping our efforts to develop the club on and off the pitch."
Jenkins was also in attendance to watch Burnley lose 2-0 to Premier League champions Manchester City at the weekend, with that result leaving them 18th in the rankings. body check tags ::
