DL Sebastian Joseph-Day Signs Two-Year Contract with Steelers

Free agent defensive lineman Sebastian Joseph-Day is signing a two-year, $11 million deal with the Steelers, offering immediate reinforcement to their defensive front. The contract includes $6 million in 2023 alone, reflecting the Steelers’ commitment to enhancing their defensive strategies. At 31, Joseph-Day brings a wealth of experience from two seasons with the Titans, where he participated in all 34 games and contributed significantly to their defense.
This move serves as a tactical hedge against potential injuries and depth concerns in Pittsburgh’s defensive lineup. The Steelers, aiming to bolster their defense in an increasingly competitive AFC, recognize Joseph-Day’s proven track record – 41 tackles, two sacks, and six quarterback hits in 2025 alone. His prior years with the Rams, Chargers, and 49ers further enhance his versatility on the field.
