A new controversy has arrived at the new doorstep of the San Francisco 49ers. It comes courtesy of the team's competitor to the north. Some Seattle Seahawks fans want to buy a commemorative brick at the new Levi's Stadium in Santa Clara. The red and gold bricks cost between $195 and $545 each - and allow fans to write three to six lines of text. Some Seahawks fans have already raised hundreds of dollars online to inscribe "Go Hawks" on a few bricks. Another brick would read, "Congrats on the second best stadium in the NFC West."Stadium officials could end up blocking fans from opposing teams from buying the bricks. Now - after an uptick in media attention - some Seahawks fans say - they'll probably scrap the trash talk, and go with something more civil.Photo Credit: Getty Images
