While few details of the arrest have been made public, Dumervil has been accused of aggravated assault with a firearm. The offense carries a possible five-year jail term.
Even if the star player manages to avoid jail time, he will still be subject to disciplinary action from NFL Commissioner Roger Goodell and a suspension would be likely.
An update on the situation, from his agent, says that no charges have been filed and no assault took place, but we'll wait for someone other than his agent to confirm that. Regardless, he likely put himself into a bad situation which was probably avoidable.
It's too early to jump to conclusions or pass any judgement, but this could be a potentially crippling blow to the Broncos, who open training camp in just 11 days.
Dumervil also had another run-in with the law in 2010 where he was accused of assault and disturbing the peace, although those charges were eventually dropped.
Added to this is the allegations that veteran linebacker DJ Williams failed multiple drug tests.
Williams had his bid to overturn the pending suspension dismissed and the Broncos are looking at being without him for up to six games.
With all of this information in mind, do the Broncos have too many liabilities on their roster?
Demaryius Thomas is coming off a season in which he caught 32 passes for 551 yards and four touchdowns, but he and former teammate Perrish Cox were recently sued (US MAG) by a woman who once accused Cox of sexual assault. Although Cox was found not guilty, she is seeking unspecified charges in the civil matter.
Besides Williams, backup tight end Virgil Green also failed a drug test and has been suspended for the first four games of the season.
So, do the Broncos have a problem, or is this all just coincidence?
More importantly, who will step up and provide a leadership role both in the locker room and on the field, especially on the defensive side of the ball, with the possibility of Williams and Dumervil missing parts of the season?
The team has Champ Bailey to help make sure a great young talent like Von Miller stays in line, but it's also on the coaching staff and the rest of the organization to ensure these players stay on the right side of the law.
The Broncos don't want to gain the reputation of being "that team," but this list is starting to pile up.
