49ers' Mark Fields: Heads to Bay Area

The 49ers claimed Fields off waivers from the Texans on Wednesday.

The 49ers are adding to their secondary depth ahead of the 2021 season. Fields has appeared in five games in his two years since entering the NFL as an undrafted free agent, so he'll likely need to prove his worth on special teams to earn a spot on the 49ers' 53-man roster coming out of the preseason.
