Waddle left Wednesday's practice early due to "some muscle tightness," Parker Gabriel of The Denver Post reports.
Analysis:Broncos coach Sean Payton said he expects Waddle to be fine. The wideout walked off the practice field earlier Wednesday, going back to the locker room without the assistance of a trainer. Waddle has often been banged up throughout this NFL career, but he's never missed time with a hamstring or groin injury -- the most common area of concern for muscular injuries with WRs.
