Waddle, who left this past Wednesday's practice with muscle tightness, didn't practice Monday, Parker Gabriel of The Denver Post reports.
That's not surprising given that coach Sean Payton said Thursday of Waddle that he thought the wideout would be back in "the next 4-to-5 days," per Aric DiLalla of the Broncos' official site. With that in mind, consider Waddle day-to-day ahead of Friday's preseason opener against the Falcons.
