Five-time Pro-Bowl DE Nick Bosa pulled his calf during Thursday’s practice and now is expected to miss “a few weeks”, in Via @AdamSchefter on X

What happened: Bosa was hurt during Thursday's practice. Per Adam Schefter, San Francisco is weighing whether to place him on injured reserve.

Why it matters: The five-time Pro Bowl selection is San Francisco's primary edge threat. An extended absence tests depth during the early regular-season stretch.

What to watch: Watch whether San Francisco uses injured reserve and who starts Sunday against Arizona.
