Demetrius Flannigan-Fowles Bio
Demetrius Flannigan-Fowles (born September 4, 1996) is an American professional football linebacker for the New York Giants of the National Football League (NFL). He signed with the Giants in March 2025 after spending his first six NFL seasons with the San Francisco 49ers. Standing 6 feet 2 inches tall and weighing around 223 pounds, he has built his professional reputation primarily through work on special teams and as a depth linebacker.
A Tucson native, Flannigan-Fowles played four seasons of college football at the University of Arizona before reaching the NFL as an undrafted free agent in 2019. Over the course of his career he has appeared in regular-season games, contributed on coverage units, and provided veteran depth at inside linebacker for one of the league’s most consistent defenses.
Early Life and Background
Demetrius Flannigan-Fowles was born on September 4, 1996, in Tucson, Arizona. He grew up in the same desert city where he would eventually begin his football career, attending Mountain View High School in Tucson. The local high school program gave him an early platform to develop as a linebacker and to attract attention from college scouts in the region.
Coming out of high school, Flannigan-Fowles was regarded as a productive local prospect rather than a national recruit. He chose to stay close to home and accepted a scholarship to play for the Arizona Wildcats, continuing his development within the Pac-12 Conference. His upbringing in Tucson and his ties to the community have remained part of his public identity.
Path to American Football
Flannigan-Fowles joined the Arizona Wildcats and spent four seasons working his way into a starting role. Over 50 collegiate games, he accumulated 243 tackles, 10 tackles for loss, three forced fumbles, two fumble recoveries, 22 passes defended, and 6 interceptions, a ball-production line that demonstrated his coverage range as a linebacker.
His ability to play in space and to contribute in the passing game helped him earn opportunities on defense and on special teams throughout his college career. Although he went unselected in the 2019 NFL Draft, his statistical production and four years of starting experience made him a candidate for a free-agent deal. On May 3, 2019, the San Francisco 49ers signed him as an undrafted free agent, giving him his first professional opportunity.
