According to Andrew Mason of MaxDenver.com, Eddie Royal and Knowshon Moreno returned to practice today:
Eddie Royal and Knowshon Moreno are practicing today. No helmets, just a walk-through. #Broncos
Moreno felt some pain in his right hamstring earlier in the week, but this is a good sign. However, with rain in the forecast on Sunday, coach McDaniels may want to be conservative with Moreno on the field.
Royal is recovering from a groin injury that may still limit him against the Niners.
