Jamaal Charles has been ruled out for Week 8 due to soreness in both of his knee.

Charles played in only two snaps last Sunday and has just 40 yards of 12 carries this season.

Coming off last year's ACL tear, Charles has been eclipsed on the field by workhorse Spencer Ware, whose 129.5 scrimmage yards per game this season rank fourth in NFL.

Ware has 35.9 percent of Kansas City's total yards in 2016.
