The Bills needed some fullback depth, and made a roster move Wednesday.
According to Mike Rodak of ESPN.com, the Bills signed fullback Sam Rogers.
They made the roster spot for him by waiving/injured fullback Zach Olstad, who had an ankle injury.
Rogers was a sixth-round pick of the Rams last year, and spent the season on their practice squad. Olstad was an undrafted rookie from Winona State.
