The 49ers’ bad year on the field could become even worse off it.

Via NBC Bay Area, the mayor of Santa Clara has threatened to seize control of Levi’s Stadium if the team doesn’t comply with contractual obligations to disclose budgetary information regarding the venue.

“We have to stop the bleeding of the General Fund money into the stadium. It’s against the law,” Mayor Lisa Gillmore said. “If they don’t cure the breach, we are going to take steps to take back management of the stadium.”

The lack of documentation prevents the powers-that-be from determining their cut of any non-NFL activities at the stadium, and to assess whether taxpayer money has been used improperly for football-related expenses, such as field maintenance. An independent auditor told NBC Bay Area that it is possible the field has been reseeded multiple times with public funds.

The 49ers said in a statement issued to NBC Bay Area that the requested information will be provided to the auditor on Monday. It’s unclear whether the team provided an explanation for the failure to make the data available earlier.
