Buffalo Bills running back Fred Jackson injured his hamstring during the team's training camp practice on Friday morning, and head coach Rex Ryan told reporters that the veteran runner is expected to miss a couple of weeks as he recovers.
Fred Jackson suffered a hamstring injury, it's not a "terrible one" but they last a couple of weeks

The Bills only just had starting tailback LeSean McCoy (toe) return to the lineup after two practices' worth of rest. Boobie Dixon could miss up to a month with a calf injury. Add in Jackson's injury and the notion that the Bills will protect McCoy for the regular season as much as they can, and the Bills are suddenly looking fairly thin at running back.
Buffalo signed undrafted Eastern Michigan running back Bronson Hill on Thursday to help bolster their body count at the position. He will see his fair share of carries in camp, but for the foreseeable future, the thinned-out depth chart will provide a golden opportunity for both Bryce Brown and Karlos Williams to impress the coaching staff as runners.
