MINNEAPOLIS (AP) - State officials say a legal challenge from a stadium opponent has forced them to delay the sale of bonds to finance the new stadium for the Minnesota Vikings.

The $468 million bond sale had been scheduled for Monday and Tuesday.

Minnesota Management and Budget Commissioner Jim Showalter says he hopes the delay will be brief.

Minnesota Sports Facilities Authority chairwoman Michele Kelm-Helgen says a longer delay would prevent the state from paying contractors for work they've already done, and jeopardize a Wells Fargo office development near the stadium.

The challenge was filed with the Minnesota Supreme Court by former Minneapolis mayoral candidate Doug Mann. He says the bond sale is unconstitutional. He says a referendum should have been held to let Minneapolis voters decide whether to finance the stadium.
