Chiefs wide receiver Dwayne Bowe has been suspended four games for violating the NFL's policy on performance-enhancing substances.
League spokesman Corry Rush announced the suspension in an e-mail, and the Chiefs have acknowledged Bowe's suspension.
In a news release, the Chiefs said Bowe’s suspension will begin immediately.
"As a result of the league suspension, the team will have no further comment," the Chiefs' news release said.
Neither the team nor the league identified the substance Bowe was accused of taking, and there are dozens of substances — steroids, hormones, beta-2-agonists, anti-estrogenic agents, masking agents and stimulants — listed among those prohibited by the league. Among the masking agents are diuretics, which some players use to help them lose weight.
Attempts to reach Bowe’s agent, Todd France, were unsuccessful on Tuesday.
Corry Rush, the AFC’s information manager, wrote in an e-mail that Bowe’s unpaid suspension would begin immediately. He’ll be eligible to return to team activities beginning Dec. 13, the day after the Chiefs play Buffalo at Arrowhead Stadium. Bowe will miss home games against Pittsburgh, Denver and Buffalo and a road game at San Diego.
That removes the Chiefs’ best wide receiver from the lineup, less than a week after coach Todd Haley said that position group had begun to make noticeable progress. Haley indicated Sunday that, along with the team’s running backs, the wide receivers had come the farthest since training camp.
