The San Francisco 49ers announced Saturday they have moved guard Alex Boone to the injured reserve list, and have promoted running back Jarryd Hayne to the 53-man roster.
Do you think Hayne will be on the active 46-man roster today against the Lions? Do you think he will return punts and/or rush the ball? Who do you think will be the 49ers’ primary running back today? Please explain your reasoning.
