Proclaiming himself sufficiently recovered from the knee and ankle injuries that kept him out of practice for much of the week, Broncos tailback Travis Henry, who is facing a one-year ban from the league for a repeat violation of the substance abuse policy, said Friday that he intends to play in Sunday's game against the Chargers. "I'm going to play Sunday," Henry said after Friday's practice, the only session in which he participated all week. Broncos coach Mike Shanahan also said that, barring any physical setback, Henry will be in the lineup against San Diego. League sources said Friday that it could be two to four weeks before the matter is resolved. During that time, it is expected that Henry will continue playing.
