Waddle, who has been dealing with muscle tightness, didn't participate in practice Tuesday, Zac Stevens of TheDNVR.com reports.
Per Stevens, Waddle was present for the session, but the wideout once again didn't work in the team's drills. Waddle remains day-to-day ahead of Friday's preseason opener against the Falcons, but given that he hasn't practiced since last Wednesday, it's increasingly likely he'll be sidelined for that contest.
