The list of teams turning down the opportunity to star in HBO’s "Hard Knocks" continues to grow, reports SportsNewser.com. The latest team to tell the network “thanks but no thanks” is the Minnesota Vikings.

Zygi Wilf, the owner of the Vikings, was asked by the Twin Cities Pioneer Press whether the organization had discussed doing "Hard Knocks." Wilf confirmed that HBO had asked the Vikings, but said the team "declined."

"We have other issues–the stadium and football–and we need to focus on those," said Wilf.

Other NFL teams that have turned down the offer from HBO to take part in the reality show include the Denver Broncos, New York Jets, Detroit Lions and Tampa Bay Buccaneers.
