Sheldon Day Bio
Sheldon Day is an American professional football defensive tackle for the Washington Commanders of the National Football League (NFL). Born on July 1, 1994, in Indianapolis, Indiana, he built his reputation as a standout interior lineman at the University of Notre Dame, where he earned second-team All-American honors as a senior. Since entering the league as a fourth-round pick in the 2016 NFL Draft, Day has built a steady career as a rotational defender with several teams, contributing on early downs and in pass-rush situations across nearly a decade of professional play.
Early Life and Background
Sheldon Day grew up in Indianapolis, Indiana, and attended Warren Central High School, one of the most prominent football programs in the state. At Warren Central, he developed into a highly recruited defensive lineman, where his combination of size, quickness, and power drew attention from major college programs. Coming out of high school, recruiting analysts considered him a four-star prospect, and he was rated as the 18th best defensive tackle in his class. On August 4, 2011, he committed to play college football at the University of Notre Dame, choosing the Fighting Irish over several other major suitors.
Path to Professional Football
Day’s path to the NFL ran directly through Notre Dame, where he spent four seasons developing under the program’s defensive staff. As a true freshman in 2012, he appeared in all 13 games and posted 23 tackles with two sacks, showing early signs of his pass-rush ability. He grew into a larger role over his next three seasons, starting games consistently and producing tackles, tackles for loss, and sacks at increasing rates. After his junior year, Day chose to return for his senior season, passing on the chance to enter the 2015 NFL Draft. That decision paid off when he delivered a career-best senior campaign in 2015, earning second-team All-American recognition from the Associated Press and positioning himself as a legitimate professional prospect.
Sheldon Day Career
Early Career (2016–2017): Jacksonville Jaguars
Day was selected by the Jacksonville Jaguars in the fourth round, 103rd overall, of the 2016 NFL Draft. As a rookie, he worked into the defensive tackle rotation in Jacksonville, providing depth behind more established veterans and contributing on running downs. Over parts of two seasons with the Jaguars, he developed his technique and adjusted to the speed of the professional game. On November 18, 2017, Jacksonville waived Day, ending his first NFL stint.
San Francisco 49ers Breakthrough (2017–2019)
On November 20, 2017, Day was claimed off waivers by the San Francisco 49ers, reuniting him with defensive coordinator Robert Saleh, whom he had worked with in Jacksonville. Day quickly became part of the defensive line rotation and finished his first stretch with the 49ers playing in six games, recording 12 solo tackles, four assisted tackles, and a sack. His most memorable moment with San Francisco came during the 2019 postseason, when the 49ers reached Super Bowl LIV. Although San Francisco ultimately lost 31–20 to the Kansas City Chiefs, Day’s role in the run to the championship game marked the deepest playoff push of his career to that point.
Indianapolis Colts Era (2020)
On March 26, 2020, Day signed a one-year contract with the Indianapolis Colts, returning to his hometown team. His season was disrupted by injury, as he was placed on injured reserve on September 6, 2020. After being designated to return later that month, he resumed practicing and was activated on October 17. Despite his return, Day was waived by the Colts on November 17, 2020, ending his brief tenure in Indianapolis.
Cleveland Browns Era (2020–2022)
On December 30, 2020, Day was signed to the Cleveland Browns’ practice squad, providing a fresh opportunity late in the season. His practice squad contract expired after the season on January 25, 2021, but he re-signed with the Browns on April 14, 2021. Cleveland terminated his contract on August 31 before re-signing him to the practice squad the following day, illustrating how roster movement is part of life for a veteran reserve. Day was elevated to the active roster on October 16, reverted to the practice squad two days later, and was signed to the active roster again on November 9. On April 18, 2022, he re-signed with the Browns for another year, though Cleveland terminated his contract on August 16, 2022.
Minnesota Vikings Era (2022–2023)
On December 14, 2022, Day was signed to the Minnesota Vikings practice squad, then released on January 7, 2023. He signed a reserve and futures contract with the team on January 30, was released on August 29, and quickly re-signed to the practice squad the next day. After another release on November 8, he returned three days later and was signed to the active roster on November 21, 2023, finishing the season in Minnesota.
Washington Commanders Era (2024–Present)
Day signed with the Washington Commanders’ practice squad on August 28, 2024, and was promoted to the active roster on October 16. On March 17, 2025, he re-signed with the Commanders on a one-year contract. Although he was waived on August 26, 2025, and briefly spent time on the practice squad, Washington signed Day back to its active roster on November 5, 2025, where he continues to provide interior defensive line depth.
Notable Events and Milestones
Day’s signature moment remains his run to Super Bowl LIV with the San Francisco 49ers, the only Super Bowl appearance of his career. Earning second-team All-American honors in 2015 stands as his most prestigious individual accolade, and his long professional journey through six organizations reflects both his durability and his value as a trusted interior reserve.

After being waived and briefly stashed on the practice squad late in the summer, he was elevated back to the active roster on November 5, giving Washington additional depth along the interior defensive line for the second half of the season. His experience on multiple defenses across the league has allowed him to step into a rotational role when called upon, contributing on early downs and in pass-rush packages.
