(AP) -- A deadline is approaching for a plan to upgrade the Edward Jones Dome and fans wonder if football in St. Louis might be at stake.

There is a Feb. 1 deadline for the St. Louis Convention and Visitors Commission to outline how it will transform the aging dome into a "first-tier" stadium by 2015.

 If it fails to do so, the Rams can break their lease after the 2014 season.

The negotiations come as Los Angeles organizers seeks an NFL team.

Rams owner Stan Kroenke has been noncommittal about the team's future in St. Louis.
