JACKSONVILLE, Fla. -

With lackluster ticket sales, the Jacksonville Jaguars are facing the potential of blackouts for every home game this season. That includes the first regular season home game Sunday.

Just days away from the opener, people aren't exactly lining up to buy tickets at EverBank Field, despite more than 7,000 seats that need to be filled to avoid a blackout.

The Jaguars organization geared up the crowd at the Jacksonville Regional Chamber of Commerce kickoff luncheon Tuesday, hoping fans make a last-minute stop at the ticket office.

"This team needs the support of those ticket holders, and the fans in the stands definitely make a difference," Jaguars Vice President of Sales and Marketing Macky Weaver said.

The Jaguars are planning to ask the NFL for an extension until Friday to sell more seats.

As a fan who finds it tough to get to the games, John Clarke said he'd be disappointed if he couldn't watch this week's rivalry with the Tennessee Titans on TV.

"You hate to miss a game like that," Clarke said.

Even Mayor Alvin Brown is hoping sales pick up, encouraging the team to make deals with faith-based organizations and the public school system.

"We all agree the Jaguars need help selling tickets. Let's have no more blackouts," Brown said.

If enough tickets aren't sold to fans, the organization says there's not much it can do because buying up thousands of their own seats is not an option.

"If the team's buying the ticket, the NFL is looking and saying, 'You know you can't sustain that way. You need the community to support you,'" Weaver said.

The Jaguars are remaining cautiously optimistic they will sell enough tickets by the end of the week.

Tickets can be purchased online at Jaguars.com, or by calling 904-633-2000 or 1-877-4-JAGS-TIX (option 4), or by visiting the Jaguars ticket office on the west side of EverBank Field. The ticket office is open from 9 a.m. to 7 p.m. on weekdays and from 9 a.m. to 2 p.m. on Saturdays.
