When the Las Vegas defense meets this week to go over Denver’s offensive personnel, the players shouldn’t have much trouble remembering the list of Broncos wide receivers. After all, Sean Payton’s team is setting out on its first game week preparations with just four on the active roster. One of them, Jerry Jeudy, injured his hamstring two weeks ago and as of Monday had not yet returned to practice. If Jeudy misses the opener — initial injury designations will be released Wednesday, but Denver is unlikely to shed much light on his status ahead of Sunday — and the Broncos don’t add to the room, their 53-man wide receivers will be Courtland Sutton, Brandon Johnson and Marvin Mims, Jr. “Everybody just has to step up and play their game,” the rookie Mims said Monday of the prospect of playing without Jeudy.
