Coach Vic Fangio said Monday that Winfree (groin) is considered day-to-day, Ryan O'Halloran of The Denver Post reports.
Winfree was only seen practicing on the side during Sunday's session, so it appears his injury isn't serious. The 2019 sixth-round pick is firmly on the roster bubble as it stands, so his ability to get healthy quickly will help his chances for a 2020 roster spot.
