49ers' Patrick Taylor: Promoted to active roster

The 49ers signed Taylor off their practice squad Wednesday.

Taylor's promotion comes as no surprise after the 49ers lost Christian McCaffrey to a knee injury and Jordan Mason to an ankle injury, temporarily leaving rookie Isaac Guerendo as the only healthy running back on the active roster. Guerendo should step in as the lead runner, but Taylor may get a decent chunk of the playing time, especially on passing downs. The 49ers also added Israel Abanikanda via waivers this week, while Ke'Shawn Vaughn is a new addition to the practice squad who could be elevated ahead of Sunday's game against the Bears if the 49ers want a fourth option out of the backfield.
