Tate's injuries not a concern for Browns?

With three seasons of NFL game action under his belt, Ben Tate has limited mileage for a 25-year-old running back, who has averaged 4.7 yards per carry. That's partly because he has worked as a backup to Arian Foster, but also due to a lengthy injury history that has kept him out of eight games. Still, Cleveland Browns coach Mike Pettine said he isn't worried about Tate's ability to hold up to the grind in an expanded role going forward.
