Denver Broncos linebacker D.J. Williams has been found guilty of driving while ability-impaired and driving without his headlights on, according to CBS Denver.

Williams, who is already suspended for six games due violating the NFL's substance abuse policy, will likely face an additional suspension, says Mike Klis of the Denver Post. That means Williams could miss most of the 2012 season.

Entering his ninth season with the Broncos, the University of Miami product has 20.5 career sacks, more than half of which have come in the last two seasons. He appeared in 13 games for the Broncos last year, including both of Denver's playoff games, registering 70 tackles, five sacks and two pass deflections and two forced fumbles. Those numbers represented a slight drop in his overall production from the previous two seasons, in which he averaged 96.5 tackles and eight pass deflections.

The Broncos signed veteran Keith Brooking a little over a week ago to help with the depth at the linebacker position, and four-year veteran Wesley Woodyard should expect to get plenty of playing time as well. The Broncos' current depth chart can be found here.
