The first-place Bears have two more regular-season contests still on the docket: a nationally televised Sunday night affair against the Rams on Dec. 9 and a Dec. 16 game against the Green Bay Packers. If the Bears win the division, Soldier Field will play host to a playoff game for the first time since Jan. 23, 2011, when Chicago fell to the Packers in the NFC championship game. LeFevour said the decreased sunlight of December means the grass grows slower, but management uses a heating system below the field to “fool the root system” and stimulate growth. Crews will only have to mow the grass about once a week late in the season, compared with about once a day during the warmer months.
