What is confirmed
Samuel left the game and was quickly ruled out for the remainder with a hamstring injury. Multiple national reporters carried the same ruling within minutes. Underdog NFL's status alert also said he would not return. San Francisco still finished the night unbeaten in a 32-29 win over Seattle.
What is still unknown
The 49ers have not said whether this is a short strain or something that will cost multiple weeks. Hamstring injuries vary widely. Some players miss one game and return the next; others sit longer. Monday's medical update and the first Week 6 injury report will set the tone. Imaging details, if any are shared, would help separate a mild tweak from a longer absence.
Why it matters for RSO rosters
Samuel remains a high-usage piece in Kyle Shanahan's offense when healthy. A multi-week absence would push more work toward the other 49ers receivers and change how SF owners build Week 6 lineups. In dynasty and contract leagues, the question is length, not whether he stays rostered.
Mike Evans was already a featured part of San Francisco's Sunday win. If Samuel misses time, that target share and the other complementary pieces become more important for the next few weeks. Owners who stashed depth behind Samuel now have a clearer reason to keep those seats warm.
What RSO owners should do
Keep Samuel rostered. Do not sell on the first report unless you already planned to move him. Watch Shanahan's Monday comments and Wednesday's practice participation. A DNP midweek would raise the odds he sits in Week 6.
If you need a short-term fill-in, look at San Francisco's other receivers who handled snaps after he exited, but wait for the first injury report before burning a claim on a one-week guess. Recheck before your Week 6 lock once the midweek report is out.
