Born to Benjamin and Rita Udoh in Fayetteville, North Carolina, Udoh attended Terry Sanford High School. He started playing football as a defensive lineman before transitioning to the offensive side of the ball as a senior, earning second team Cape Fear Region honors after helping the program reach the playoffs for the second consecutive year. Udoh was a NCHSAA student-athlete honoree in both 2012 and 2013 and also lettered in track and field in his final season, recording a top-throw of 44'5" (13.54m) in the shot put.[1]
On October 31, 2022, Udoh was arrested during the Vikings' bye week for falsely being accused of following a woman into a bathroom at a bar and refusing to leave and was charged with disorderly conduct and resisting arrest. The charges were later dismissed and his lawyer characterized the arrest as unlawful due to the evidence proving that he never entered the bathroom with a woman.[10][11]
In May 2023, Udoh was cited on three separate occasions for traffic violations. Two of these incidents were for speeding, including driving 97 MPH in a 55 MPH zone on I-94 in St. Paul, Minnesota. He was also charged with reckless driving in a separate incident two days later.[12]
