The fifth-round selection out of Alabama has made an immediate impact on Chicago's No. 1-ranked defense, leading the team and all rookies with 7.5 sacks, the most sacks through a rookie's first seven games in NFL history.
Mark Anderson recorded 6.0 sacks in October, the most by a rookie and tied for second overall in the NFL. The defensive end posted a sack in all four games during the month, including multiple-sack contests against Seattle (October 1) and Buffalo (October 8), as the Bears won all four games to improve to 7-0 on the season.
Anderson forced three fumbles, including one against Arizona on Monday Night Football (October 16) that led directly to a defensive touchdown, and had a forced fumble in each of the final three games of the month.
For October, Anderson totaled 16 tackles as the Chicago defense allowed an NFL-low 923 total net yards (230.8 yards per game) and was third with 46 points allowed (11.5 points per game). The Tulsa, Oklahoma native is currently on pace to set a new rookie record for sacks, surpassing Jevon Kearse's mark 14.5 in 1999.
Anderson is the first Bears defensive player to earn a Rookie of the Month Award since Brian Uralcher in October of 2000. New Orleans Saints wide receiver Marques Colston was the American Football Conference (AFC) Rookie of the Month.
