a result, the Chicago Bears' first home game of the season against the Philadelphia Eagles was played at Northwestern University's Dyche Stadium. The Bears also treated this game as a trial run for possibly moving their home games to Evanston. Dyche Stadium (since renamed Ryan Field), also did not have lights at the time (nor does it have permanent standards today), was it was still planned to make the Bears' new home. But a deal fell through due to strong opposition from several athletic directors in the Big Ten Conference and residents of Evanston. After negotiations with the Cubs' ownership for continued use of Wrigley Field collapsed, the Bears moved to Soldier Field in 1971 where they remain to the present day, save for a temporary relocation in 2002 to the University of Illinois' Memorial Stadium while Soldier Field was completely renovated.
