It appears Buffalo Bills running back Fred Jackson may still be another week away from returning to game action.

Although he participated in practice for the second consecutive day Thursday, head coach Doug Marrone indicated that Jackson is still not ready to play, according to the team's official website.

It would certainly hurt the Bills' offense to go without the reliable veteran for Sunday's matchup with the Kansas City Chiefs, but holding him out until the Thursday night game to follow may be the best course of action.

Prior to being sidelined, Jackson had tallied 55 carries for 239 yards and one touchdown.
