The Denver Broncos began preparation for their second game of the preseason over the weekend. The Broncos emerged from Thursday’s 31-3 win over the Chicago Bears mostly unscathed. Fullback Chris Gronkowski, linebacker Danny Trevathan, and tackle Chris Clark all left the game with injury, and will be evaluated further today. The Broncos are gearing up for their first home game of the season, a Saturday night clash with the Seattle Seahawks, who beat Tennessee 27-17 in their preseason debut Saturday.
