What happened: The 25-year-old reunites with Robert Saleh after spending last season in San Francisco. The 49ers released him last week.
Why it matters: Tennessee also signed Mario Goodrich and waived Jeadyn Lukus earlier Sunday. Canteen joins the preseason competition for a roster spot.
By the numbers: Canteen appeared in no regular-season games in 2025. His college stops were Georgia Southern (2019-22), Virginia Tech (2023) and Cincinnati (2025).
What to watch: Watch where Canteen slots into Tennessee’s secondary rotation during preseason practices.
