Stafford isn't present for Wednesday's practice, Chris Burke of The Athletic reports.
Stafford has played every offensive snap for Detroit this season, and he hasn't been listed on the injury report at any point. That could change later Wednesday when Detroit releases its first Week 9 report, though it's possible he was excused from practice for non-injury reasons. Whatever the case, Chase Daniel and David Blough are splitting quarterback reps during Wednesday's practice.
