Dolphins head coach Mike McDaniel said Wednesday that he's "not really worried about the timeline" of Waddle progressing through the NFL's five-step concussion protocol, Joe Schad of The Palm Beach Post reports.
Waddle didn't practice Wednesday but did participate in team stretches, according to Cameron Wolfe of NFL Network. He will have two more chances to take the practice field before receiving a game designation for Sunday's matchup against the Broncos, but Waddle looks uncertain to clear the protocol in time for the Week 3 matchup. If Waddle is ruled out this weekend, there will be an opportunity for Braxton Berrios, River Cracraft and Erik Ezukanma to step up behind top wideout Tyreek Hill.
