Bears President Ted Phillips recently met with Chicago Park District general superintendent Tim Mitchell about the possibility of converting the field from grass to an artificial surface, but there are no plans to do so this year. The Park District was interested in changing the surface ? despite a busy summer schedule at the stadium that includes five concerts ? but the Bears indicated they aren't. One of the complicating factors is the Bears still are awaiting results of a league study on injuries incurred on infill playing surfaces. "The Chicago Bears will always put a premium on player safety," Phillips said in a statement to the Tribune. "Each year we will continue to discuss the pros and cons of grass and infill surfaces, and then make a decision."
