Big Cat Country has learned that the Jacksonville Jaguars practice fields will be sponsored as well. Blue Cross Blue Shield will be sponsoring the practice facilities adjacent to the stadium.
The terms of this deal are not yet known, and will possibly be revealed at the press conference today at 3P.M.
UPDATE 2:27 PM EST: According to Mike Dempsey of 1010XL WJXL, the practice field will be called "Blue Field".
I am also trying to verify that the Jaguars will have patches on their practice jerseys, thanks to a tip from a BCC commenter.
