Mason has been operating as the 49ers' third running back during offseason activities, Jerry McDonald of The San Jose Mercury News reports.
Mason's standing on the depth chart shouldn't come as a surprise following his strong showing on special teams and as a reserve option out of the backfield in 2022. The then-undrafted rookie quickly surpassed third-round pick Tyrion Davis-Price on the depth chart, and he appears set to maintain that position as the two battle for spots behind starter Christian McCaffrey and top backup Elijah Mitchell.
