It looks like Mike Zimmer will avoid having to make a return appearance on Hard Knocks.
NFL rules say the Vikings could be compelled to appear on the popular HBO show, but a report by ESPN Cleveland indicates Minnesota is not among the teams currently being considered for the upcoming season.
The report says HBO would prefer to work with a team that willingly volunteers to be on the show (rather than one that is forced to do against its will), and says the network is currently considering three teams for this summer: Washington, Buffalo and Houston.
