Los Angeles (AFP) - Indianapolis Colts linebacker D'Qwell Jackson has been suspended by the NFL for four games for violating the league's policy on performance-enhancing substances.
The NFL made the announcement Tuesday, and the suspension begins immediately for Jackson, who will be eligible to return to the active roster on January 2 -- if the Colts qualify for the playoffs.
The 6-6 Colts are locked in a three-way tie with the Houston Texans and Tennessee Titans atop the AFC South division.
In 12 games this season Jackson has posted a team-best 78 tackles, one sack and three pass deflections.
The 33-year-old is in his third year with the Colts after playing his first eight NFL seasons with the Cleveland Browns.
