According to Jack Hammer of the Santa Rosa Press Democrat, 49ers WR Brandon Aiyuk (shoulder) had a CT scan yesterday that revealed no break in his clavicle area.

The prevailing wisdom is that, if Aiyuk’s CT scan revealed no break, he is most likely dealing with an AC sprain. While the team has stated that his ability to play on Thursday will be “all about pain tolerance,” an injury to the AC joint will make it difficult to reach out to make catches and could also create pain if he were to land on his shoulder. When Mark Andrews sprained his AC joint last year, he missed a little over a week while more severe sprains have kept players out for up to a month. All of which makes Aiyuk’s status for Thursday Night Football feel precarious.
