The 49ers announced a pair of roster moves on Thursday.
Offensive tackle Kion Smith has signed a contract with the team. Wide receiver Colton Dowell was waived to open up a spot for Smith.
Smith signed with the Falcons after going undrafted in 2021 and moved on to the Dolphins later that year. He remained in Miami through the 2025 season and appeared in 23 games. Smith's only two starts came during the 2025 season.
Dowell signed with the 49ers in January. He was a Titans seventh-round pick in 2023 and caught one pass for three yards in 10 games during his rookie season.
