Coach Kyle Shanahan said Monday that Green (back) is considered day-to-day ahead of Sunday's game at Dallas, Matt Barrows of The Athletic reports.
Green sustained a back injury during San Francisco's win versus the Raiders in Week 9, and now his availability for Week 10 is in question. His activity at practice will be worth monitoring over the course of the week, and the 49ers' first official injury report of the week Wednesday should provide further insight into his status.
