Tonight's the night for Chief Illiniwek's last performance, during the halftime at the Illinois-Michigan game. After the Chief is retired, the Illini logo featuring the chief will eventually also be retired, although the State Journal-Register reports that the school is trying to develop a phase-out plan to make sure the logo doesn't fall into disuse and enter the public domain, allowing any old manufacturer to use it on their products. In the meantime, the Illini gear with the chief logo is flying off the shelves at the school's store.
