Teamer has been out of action since Week 6 with a hamstring injury, although he was reinstated from IR on Saturday, before ultimately not suiting up for Sunday's loss to the Chiefs. The 26-year-old was arrested for a DUI early that morning, which likely played a part in him being inactive for the contest.
Teamer was reinstated from injured reserve Saturday after being a full participant in practice all week. Though Teamer was listed as questionable and expected to play Sunday against the Chiefs, Bonsignore notes that the Raiders' decision to downgrade the reserve safety comes after he was arrested early Sunday on a DUI charge.
