NASHVILLE, Tenn. (AP) -- Tennessee rookie running back Chris Henry faces a four-game suspension for a violation of the NFL's banned substance policy.

Henry officially will be notified of the suspension Saturday and have up to five days to appeal the penalty in a story ESPN.com first reported Friday night. A team spokesman had heard the reports but declined to comment. Henry's agent could not be reached immediately for comment.

The subsance reportedly was not performance enhancing and had been added to the list of banned substances within the past year, ESPN.com reported, citing unnamed sources.

Henry, the Titans' second-round draft pick out of Arizona, has played in each of the past two games with veteran Chris Brown sidelined by a high ankle sprain after being deactivated the first five games. With time to appeal, he should be able to play Sunday against Carolina (4-3).

Starter LenDale White missed practice Friday with a toe problem.

Henry has filled in for him and ran for 48 yards on four carries, including a 24-yard touchdown last week.

"I feel different now than I did in the preseason. I just came in and relaxed and ran," Henry said after practice Friday before the suspension was reported. "I wouldn't say I was even hesitant. I think I was more getting the feel for running with the new offensive line at game speed. Now I just let it go and go out and play."
