The 49ers don’t know who their right guard will be against the Detroit Lions on Sunday. The top-three options are working back from injuries, while a recent practice squad player on Wednesday was seen taking first-team reps.
Week 1 starter, Mike Person, spent Wednesday’s session on the side field after suffering a foot injury in Minnesota. Joshua Garnett was in the weight room hobbling around with a pronounced limp after separating a toe in Person’s stead.
On the bright side, Erik Magnuson participated during individual drills for the first time Wednesday since suffering a hamstring strain in the second preseason game.
