Waddle was limited at Wednesday's practice due to a chest injury, Aric DiLalla of the Broncos' official site reports.
Waddle missed a brief spell in last Thursday's win against the Seahawks due to a shoulder injury, finishing Week 6 with four catches (on seven targets) for 24 yards. Almost one week later, he's tending to a chest issue, meaning his status will be watched closely as the weekend draws closer.
