The 49ers, who have a short turnaround this week, suffered injuries to two starters in Sunday’s 23-7 victory over Arizona. Fullback Bruce Miller suffered what the team described as a “head injury” in the second quarter and did not return.
If Miller is out for Thursday’s game in Baltimore, Moran Norris would start. Meanwhile, tackle Anthony Davis sprained his right ankle in the third quarter when an opponent rolled onto it in a pile. He briefly returned to the game but was replaced for the remainder by Alex Boone, who would start in Baltimore if Davis can’t play.
