Miller was originally suspended four games for violating the NFL's substance abuse policy and an appeal hearing that was scheduled for last Thursday was postponed.
"We haven't been aware of really any of it to be honest with you," Broncos head coach John Fox said Monday. "We don't know the suspension. There is no suspension and at which time there is we'll report that, but anything else right now is really just talking heads."
Miller is also facing further discipline following his recent arrest for failing to appear in court for an outstanding warrant.
The Broncos led the league with 52 sacks last season, and Miller had 18.5.
Broncos defensive end Derek Wolfe was categorized as "day to day" by Fox. Wolfe was taken off the field by ambulance in Seattle on Saturday night and treated for a cervical spine injury, but had movement in all of his extremities.
All tests were negative and Wolfe returned to Denver with the team on Saturday evening.
Broncos cornerback Champ Bailey is also day to day with a sprained left foot, leaving his availability for the regular-season opener in doubt.
Even though he will be sidelined until next month, Blaine Gabbert was named the starting quarterback for the Jacksonville Jaguars.
Head coach Gus Bradley declared Gabbert the No. 1 quarterback over Chad Henne, ending a competition that began in in April.
A hairline fracture in his thumb will force Gabbert to sit out the remainder of the preseason.
Bradley said Gabbert will be ready for the regular-season opener against the Kansas City Chiefs.
Injured New England Patriots tight end Rob Gronkowski is not expected to be healthy enough to return when the team opens the season against the Buffalo Bills, ESPN reported.
Gronkowski had offseason back and forearm surgery and was hoping to make it in time for the first game of the season.
Patriots quarterback Tom Brady spoke publicly about his knee injury for the first time, saying it was not a big deal.
Brady's left knee was hurt during practice last Wednesday, but returned to practice Thursday and played Friday's preseason game against the Tampa Bay Buccaneers.
He told Boston radio station 93.7 WEEI on Monday that he "felt bad it caused more of a media story than it actually was", according to ESPNBoston.com.
Former first-round pick A.J. Jenkins was traded from the San Francisco 49ers to the Kansas City Chiefs in exchange for wide receiver Jonathan Baldwin, another failed top pick.
Jenkins dropped the only pass intended for him in a regular season game as a rookie. He had only one catch this preseason and it resulted in a fumble.
The Tennessee Titans activated tight end Delanie Walker from the physically-unable-to-perform list.
Walker was placed on the PUP list at the start of training camp after having arthroscopic knee surgery.
A doctor told the Cleveland Plain Dealer that Cleveland Browns rookie Barkevious Mingo, who sustained a bruised lung during last week's preseason game, could have died.
Dr. Clark Fuller, Director of Thoracic Surgery at Saint John's Health Center in Santa Monica, Calif., has not treated Mingo, but said if he had remained in Thursday's 24-6 victory over the Detroit Lions and taken another hit to the chest, it could have killed him.
Mingo is expected to be ready in time for the Browns' regular-season opener Sept. 8.
Quarterback Seneca Wallace was released by the New Orleans Saints, who now have veteran Luke McCown and undrafted rookie Ryan Griffin on the depth chart behind Drew Brees.
The Jacksonville Jaguars announced that they released wide receiver Mohamed Massaquoi and guard/center Jason Spitz.
Massaquoi has 118 receptions for 1,745 yards with seven touchdowns in four NFL seasons, all with the Cleveland Browns. He had 17 catches for 254 yards last year.
Offensive guard John Moffitt was acquired by the Cleveland Browns, who sent defensive lineman Brian Sanford to the Seattle Seahawks. Moffitt has started 15 of 17 career games he has played in.
Less than a year after the Detroit Lions acquired wide receiver Mike Thomas, they released him, NFL.com reported Monday.
Thomas caught 158 passes in his first three NFL seasons for the Jacksonville Jaguars.
The Lions traded a 2014 fifth-round draft pick to the Jaguars to get him at midseason last year. Thomas caught only five passes in nine games in 2012.
