Johnson was forced to leave Thursday's win over the Raiders after rupturing his Achilles, Terez A. Paylor of the Kansas City Star reports.

EDGE Analysis

Head coach Andy Reid confirmed Johnsons' injury following the game. The Chiefs' all time leader in tackles will presumably have his season ended for the second time due to an Achilles injury. Either D.J. Alexander or Terrance Smith figure to replace the veteran at inside linebacker going forward.
