49ers Lose Bosa and Juszczyk for Seahawks Clash, But Mike Evans Returns

The San Francisco 49ers are heading into one of the loudest buildings in the NFL without two of the guys who actually make their physical identity work. ESPN's Adam Schefter reported Friday that fullback Kyle Juszczyk and defensive end Nick Bosa are officially ruled out for Sunday's divisional clash against the Seattle Seahawks.

The silver lining for San Francisco is that wide receiver Mike Evans is completely off the injury report. Having a massive target with no injury designation is a huge relief for a passing game that is going to need to keep pace in a hostile environment.

"Adam Schefter reported the injury updates via Twitter."

Losing Bosa and Juszczyk in the same week is like trying to win a bar fight without your bouncer or your brass knuckles. Bosa is the engine of the pass rush, and Juszczyk is the skeleton key that unlocks the entire San Francisco rushing attack.

Both teams are coming off solid wins on October 4, with the 49ers handling the Denver Broncos 24-14 and the Seahawks taking down the Los Angeles Chargers 30-23. Seattle already had momentum, and now they get to face a San Francisco defensive front missing its most terrifying piece.

For anyone looking at the lines, the absence of Bosa fundamentally changes how you have to evaluate the Seattle offensive line's chances of keeping a clean pocket. You do not just replace a guy who lives in the opponent's backfield, and you definitely do not easily replace the fullback who makes the entire offensive scheme tick.

Sunday night in Seattle was already going to be a heavyweight fight. Now, the 49ers have to prove they can still bully a division rival without their two biggest bullies on the field, while leaning heavily on Evans to make the difference on the outside.
