DENVER -- Denver Broncos running back Travis Henry has reportedly tested positive for marijuana and faces a year suspension. Henry is embroiled in a lawsuit to keep the NFL from using the results of a drug test to suspend him, according to court papers filed in Brooklyn federal court.

Henry fired the first salvo in the case Sept. 20 when he attempted to get a restraining order in Suffolk County Supreme Court to block the NFL from using a urine specimen against him and to stop the league from disclosing the test results.

Newsday.com is reporting Court papers filed in the state court action couldn't be reviewed late Thursday, and Henry's attorney Robert Dapelo of Patchogue declined comment. But papers filed by the NFL on Monday in federal court suggested that Henry may have failed the test because the documents stated that Henry was trying to stop the league from testing his specimen and "suspending from his employment with the NFL."

While the Suffolk court granted the temporary restraining order against the NFL, the league got an appellate court to vacate that order, court papers disclosed.

The NFL is seeking to have the litigation transferred to Brooklyn federal court because the issue involves interpretation of the league's collective bargaining agreement, which generally is covered by federal labor laws. Henry claims that the NFL violated league substance abuse policy by not allowing his experts to be present for testing of his urine specimen, court papers stated.

The 28 year-old Henry was signed by the Broncos in March after stints with the Tennessee Titans and Buffalo Bills. He leads the league in rushing this season with 433 yards.

NFL attorney Sean O'Donnell of Manhattan declined to comment late Thursday.
