The San Diego Chargers received only 42.5 percent approval on Measure C, the team's $1.8 billion downtown stadium and convention center annex that proposed raising hotel taxes from 12.5 percent to 16.5 percent to secure $1.15 billion in bonds to help pay for the project on Tuesday.

The citizens' ballot initiative required two-thirds of the voting public within city limits to approve the project.

In a letter sent late Tuesday night, club chairman Dean Spanos thanked season-ticket holders and fans for their support but offered no insight into his intentions moving forward.

"In terms of what comes next for the Chargers, it's just too early to give you an answer," Spanos wrote. "We are going to diligently explore and weigh our options, and do what is needed to maintain our options, but no decision will be announced until after the football season concludes and no decision will be made in haste."
