Waddle, who left Wednesday's practice with muscle tightness, is present for Thursday's session but appears to be an observer, Parker Gabriel of The Denver Post reports.
Analysis:Per Chris Tomasson of The Denver Gazette, while the wideout was spotted during the initial portion of practice Thursday, he wasn't wearing his helmet, then subsequently worked on a side field. Still, Waddle's presence, in any capacity, suggests that Wednesday's muscle tightness isn't a concerning issue and that he should be considered day-to-day for now.
