Two years ago, Broncos pass rusher Von Miller was suspended six games for violating the NFL’s substance abuse program, and missed nearly half the 2013 season. However, last season, he played all 16 of Denver’s regular season contests, and a source tells Mike Klis of 9NEWS that after not testing positive for two years, Miller is no longer in the league’s drug program.

Typically, multiple positive tests result in harsher and harsher penalties for players, as we’ve with someone like Josh Gordon. But a positive test for Miller at this point wouldn’t result in significant discipline, since his status has been reset, writes Klis. It’s an extremely positive development for Miller as he enters a contract year, since the Broncos will have less reason to be concerned about him missing games in the future, making the team more likely to offer him a lucrative extension.

Here’s more from around the AFC:

• Chargers quarterback Philip Rivers confirmed today that there are no new developments on the contract extension front, tweets Alex Marvez of FOX Sports. According to Rivers, the two sides will likely shelve negotiations until 2016 if they don’t reach an agreement within the next 10 or 12 days.
• According to Vic Carucci of The Buffalo News, Marcell Dareus seems encouraged by the progress that has been made in contract discussions between him and the Bills, joking that he owes a thank-you to Ndamukong Suh for resetting the market this offseason.
• Jets GM Mike Maccagnan expressed support for Sheldon Richardson following his recent arrest, indicating that he and the Jets will devote resources to helping the standout defensive lineman, as Rich Cimini of ESPNNewYork.com outlines. However, Maccagnan was noncommittal on Richardson’s long-term future with the Jets, and acknowledged that there’s “a degree of trust that has been broken.”
• Chargers defensive end Tenny Palepoi suffered a fractured foot, and will likely be sidelined for two months, a source tells Michael Gehlken of the San Diego Union-Tribune. Depending on how Palepoi’s recovery progresses, he could be a candidate for the injured reserve list with the designation to return, though the Chargers may prefer to save that one-time designation for someone else.
