Broncos receivers Emmanuel Sanders and Isaiah McKenzie will miss this Sunday's game against the Chargers with sprained ankles.
The Broncos and wide receiver Demaryius Thomas have not exchanged contract proposals or had any dialogue in more than a month, sources tell ESPN's Adam Schefter.
If Dez Bryant and Demaryius Thomas don't sign long-term deals by Wednesday's deadline, the NFL players' union plans to move ahead with collusion charges against their respective teams.
The NFLPA is reviewing information to determine whether there was collusion between the Broncos and Cowboys on the unsettled contractual situations of Demaryius Thomas and Dez Bryant.
Emmanuel Sanders said anything outside of a championship would be "a bust season" for the Broncos after new coach Gary Kubiak showed the team a video with big plays from the last 20 Super Bowls.
Demaryius Thomas will not attend the Broncos' offseason program and will not take part in workouts at Duke University with quarterback Peyton Manning and the team's other wide receivers.
