49ers add OL Kion Smith on a one-year deal, waive WR Colton Dowell

The San Francisco 49ers announced on August 6 that they have signed offensive lineman Kion Smith to a one-year deal and waived wide receiver Colton Dowell to make room on the roster. The move adds another option in the trenches as the team works through the late-stage roster process that typically includes balancing starters, depth, and special-teams considerations.

Smith’s signing places a new body in the 49ers’ interior and line-protection picture. Offensive line depth is a central part of NFL roster construction because teams need reliable options across multiple blocking schemes and game situations, especially over the course of a long season where injuries and matchups can force lineup changes. A one-year contract also reflects the team’s desire to evaluate fit quickly while maintaining roster flexibility.

Dowell, meanwhile, leaves the roster in a corresponding transaction. The 49ers’ release indicates the waiver was specifically to create space, a detail that underscores the mechanics of NFL roster management rather than any single isolated performance judgment. For a wide receiver, opportunities often hinge on availability, route consistency, and how well a player can contribute in special teams roles. Waived players can still attract interest from other clubs, but the 49ers’ immediate priority is clearing a spot for Smith.

Taken together, the transaction is consistent with how teams tend to manage camp and pre-season roster churn. Even successful rosters require repeated evaluation, and adding linemen late can be especially strategic if coaching staff want more competition at positions that can determine protection quality and the effectiveness of the running game.

For Smith, the path to meaningful snaps will likely depend on how well he handles the day-to-day demands of run blocking and pass protection, along with his ability to learn and execute the team’s assignments. The 49ers also may view the signing as a way to increase competition among backup linemen, a common objective when teams enter the stretch where depth chart roles become more defined.

For Dowell, the waiver means he is now looking for his next opportunity. In the NFL, wide receivers who clear waivers or are claimed by another team can still find ways into rotation depending on injuries, offensive scheme fit, and special-teams needs.

As the 49ers move forward, fans should watch for how Smith is used during team activities and how the waiver creates ripple effects across the receiving room. Roster moves like this can subtly shift practice competition and can be an early indicator of what the team values most as it trims down toward the season-opening group.
