Former Denver Broncos running back Travis Henry was arrested yesterday by the Drug Enforcement Agency after an alleged "multikilogram" cocaine transaction in Centennial, Colo.

Henry, who is not with a National Football League team this season, and James Mack are being held pending the filing of federal drug charges in U.S. District Court in Denver later today, the DEA said in a news release.

A telephone message left for Henry's agent, Hadley Engelhard, wasn't immediately returned.

Henry, 29, played 12 games for the Broncos last season, starting 7, after stints with the Tennessee Titans and Buffalo Bills during his 7-year NFL career. He has rushed for 6,086 yards and 38 touchdowns.

In December, he successfully appealed a failed drug test that would have cost him a one-year suspension from the NFL, claiming that a positive test for marijuana was due to secondhand smoke. He agreed to lie-detector and hair-sample tests to prove his innocence to Broncos coach Mike Shanahan. He passed both of those examinations.

Henry was suspended by the NFL for four games in 2005 for repeat violations of the league's substance-abuse policy and by league guidelines would have been given a one-year ban for another positive test within two years.
