San Francisco 49ers wide receiver Deebo Samuel will be sidelined for at least a couple of weeks after suffering a hamstring injury in Sunday’s 32-29 win over the Seattle Seahawks. Samuel was ruled out before halftime and did not return, and head coach Kyle Shanahan confirmed Monday that the injury “got him pretty good.”

Samuel underwent an MRI on Monday to determine the full extent of the damage, and while the team has not released a formal return timetable, Shanahan’s “at least a couple of weeks” estimate puts Samuel’s return realistically in the Week 7 or Week 8 range. That timeline would cost him Monday night’s home matchup with the Washington Commanders in Week 6 and likely the following week’s road trip to face the Atlanta Falcons as well.

A Costly Blow for the NFL’s No. 1 Offense

The injury comes at a brutal time for San Francisco, which improved to 5-0 with the win in Seattle and sits at No. 1 in Pro Football Talk’s Week 6 power rankings. Samuel has been a key piece of that start, posting 16 catches for 206 yards and three touchdowns through five games in his return to the Bay Area this season. He has also chipped in as a runner, with nine carries for 78 yards, continuing the dual-threat role that has defined his career since his All-Pro 2021 campaign.

San Francisco already has been without Christian Kirk, who remains on injured reserve with a calf injury and is not expected back for Week 6. With Kirk out and now Samuel joining him on the sideline, the 49ers’ receiver room thins out considerably behind Mike Evans. Brandin Cooks, Jacob Cowing and Jordan Watkins are the next men up, with Cooks in line for an expanded role after scoring a touchdown in the win over Seattle. Shanahan will lean on that trio, along with the team’s run game and tight ends, to keep the offense humming while Samuel recovers.

The 49ers were also dealt a secondary blow in the same game, as backup linebacker Garret Wallow suffered a less severe hamstring injury of his own and is considered questionable for the short term as well.

Betting Angle: Favorites Status Holds, But Markets Will Be Watching

San Francisco opened as home favorites over Washington for Monday Night Football in Week 6, and early lines had the 49ers positioned around a touchdown-plus favorite with a heavily lopsided moneyline reflecting their perfect start. Samuel’s absence is the kind of news that oddsmakers and bettors alike will monitor closely as the week progresses, since losing a dual-threat weapon who touches the ball in the passing and running game alike can chip away at an offense’s explosiveness, even one as potent as Kyle Shanahan’s.

On the futures side, the 49ers have climbed into the top tier of Super Bowl odds boards this season, with some books pricing them among the top handful of contenders in the league. Any uncertainty around a core playmaker’s health is worth watching for bettors tracking those longer-term numbers, since win totals and conference odds tend to react to sustained injury concerns on a 5-0 team more than to any single game’s point spread. If Cooks and Cowing step in and the offense doesn’t miss a beat over the next two weeks, expect the futures market to shrug off the news. If San Francisco’s passing attack bogs down without Samuel’s run-after-catch element, that’s when a more meaningful market correction could follow.

Prop bettors will also want to note the ripple effects: with Samuel out, increased target share for Cooks and Cowing could make their receiving yardage and reception props more appealing in the short term, while Samuel’s own season-long touchdown and yardage props take a hit until he’s back on the field. For a 49ers team trying to hold its position as the league’s top-ranked squad, how the receiver rotation performs over these next couple of weeks will carry real weight for anyone tracking San Francisco’s odds to win the NFC West, the NFC, or the Super Bowl.
