The NFL has suspended Denver Broncos safety Kareem Jackson for the final two regular season games for violating the league's substance abuse policy. Jackson was arrested Sept. 19 on suspicion of driving under the influence and he has since pleaded guilty to one count of driving while alcohol impaired. Denver signed Jackson to a three-year, $33 million contract last offseason. Jackson has two interceptions for a Broncos team that's ensured of a third straight losing season. The 31-year-old Jackson was suspended without pay.
