Vikings running back Adrian Peterson and Titans quarterback Vince Young are working out together in Houston. Tennessee maintains that Young won't return to the team next season. KPRC in Houston reported that Peterson and Young have been working out together with other players. "It's been that way," Young said Tuesday. "Adrian and the other guys are here to work. It's a good time out here then we lift together, eat lunch, bond and build chemistry. Keeping that football brotherhood is what it's all about."
