Mike Evans ruled out already on a Thursday...Achilles tendinitis at 33 years old...I would assume if he's getting ruled out this early...I don't think you're getting Mike Evans for a couple weeks here. I would assume if you have Evans, not only is he missing weeks nine, but maybe 10 and 11 as well...I think there is a non-zero percent chance that Mike Evans, Devonta Smith are done for the year...there's a good chance that Evans is missing a long time here and we don't know if he is going to make a difference, but it's a free upside shot.
STACKED’s take
Achilles tendinitis likely sidelines Evans weeks 9-11; non-zero season-ending risk but free upside in trades.
Ruled out Thursday for week 9 with Achilles tendinitis at age 33. Bam Knight expects Evans to miss weeks 9, 10, and 11, potentially not returning until week 12 division game vs. Seattle; early Thursday ruling-out suggests no practice attempts, indicating multi-week absence rather than single-week miss. Knight ranks Evans ahead of DeVonta Smith with expectation Evans has a chance to play this week, but expresses serious concern about season-ending risk, estimating non-zero percent chance Evans could be done for the year. The 49ers trying to win a Super Bowl may increase likelihood they rest Evans if injury is severe. However, Knight frames Evans as a free upside shot in trade scenarios where he can be added without significant cost, suggesting fair value as an add-on piece to balance injury risk concerns.
