The Miami Dolphins have agreed to seek voter approval of tax dollars for Sun Life Stadium, with team executives dropping their objections to a referendum on the controversial plan, sources close to the matter said Saturday.

The Dolphins and County Mayor Carlos Gimenez expect to announce the referendum agreement on Monday, The Miami Herald has learned. Sen. Oscar Braynon, the Miami Gardens Democrat sponsoring a bill to bring Sun Life new state and county subsidies, would then change the proposed legislation to require a countywide vote on the plan, a source familiar with the Dolphins’ lobbying efforts said.

The Dolphins hope to get the issue before voters by May 22, when the NFL is expected to pick the host city for the 2016 Super Bowl, the 50th. The Dolphins have cited the bid to host that game as the reason to push for a quick decision on tax dollars to pay for about half of a proposed $400 million renovation.

Team owner Stephen Ross rejected the idea of a referendum as recently as last month, saying there wasn’t time. The apparent change in course comes days after Miami-Dade lawmakers left the stadium bill off their official list of priorities for this session in Tallahassee, a move that critics of the plan hailed as a big blow to the team’s chances in a Legislature already opposed to raising taxes.

By agreeing to a referendum, the Dolphins would test the lingering backlash against the 2009 deal that gave the Marlins a new ballpark largely funded by taxpayers. The Dolphins see their plan as more palatable, since Ross has agreed to use private dollars to pay for at least $201 million of the project, with state and county funds paying no more than $199 million.

Ross would likely use a mix of team and NFL funds, and some finance authorities have said NFL money could match the Dolphins’ contribution dollar for dollar.
