Waddle, who has been dealing with muscle tightness, didn't participate in practice Tuesday, Zac Stevens of TheDNVR.com reports.
Waddle was present for Tuesday's session but didn't work into team drills. The former Dolphin 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.
