Tamarick Vanover and Bam Morris, members of the Chiefs this season, have been linked to a federal drug investigation that affidavits say extends to Mexico and includes "numerous states."
FBI spokesman Jeff Lanza said neither had been charged.
An affidavit naming Vanover and Morris was filed in federal court Jan. 25 in connection with the case of Greg Burns.
Burns, described in the affidavit as Vanover's personal assistant, was charged last week with conspiracy to distribute marijuana and said to be "a significant cocaine and marijuana supplier in the Kansas City metropolitan area."
The affidavit, signed by FBI agent Larry G. Tongate, says Vanover's house had been under surveillance since April.
Morris, a sixth-year running back who unexpectedly retired less than two weeks ago, twice was suspended by the NFL for substance abuse while with the Pittsburgh Steelers. He spent 89 days in jail in Texas for violating terms of the probation he was given in 1996 after pleading guilty to marijuana possession. He had been arrested near Rockwall, Texas, with 6 pounds of marijuana.
Tongate said in the affidavit that he had received information about "the drug distribution activities" of Vanover and two people not associated with the Chiefs.
Morris' agent, Terry Lavenstein, told radio station WHB, "Bam Morris, as far as we know, is not involved in any activity in this ridiculous story."
JETS: Dan Henning was named offensive coordinator to replace Weis. Henning was the quarterbacks coach the last two seasons.
COWBOYS: Coach Dave Campo hired former quarterbacks coach Jack Reilly to be offensive coordinator, and secondary coach Mike Zimmer was promoted to defensive coordinator. Reilly spent the past two seasons as quarterbacks coach for the Patriots.
REDSKINS: The team re-signed fullback Larry Centers to a four-year contract, 10 days before he would have become a free agent. The Washington Post said the deal worth around $6-million. Centers led Washington this season with 69 receptions for 544 yards.
