Chiefs linebacker Lew Bush is blaming a poorly labeled supplement for his four game suspension, which was handed down yesterday by the NFL. Bush tested positive for the stimulant ephedrine. Bush’s agent says the banned substance was not listed as an ingredient in an over the counter product Bush was taking. He plans on appealing the decision. In the meantime, Glenn Cadrez will move into his back up linebacker spot. Earlier this season, Bush lost his starting linebacker spot to rookie Scott Fujita. Bush has 10 tackles on the season. If the suspension stands, Bush will be available for the December 1 game against the Cardinals.
