Thomas suffered a hip injury in Denver's Week 5 loss at New England, but he played every snap. Clady injured his knee and also didn't miss any time, and the availability of both players for Monday isn't known.
Thomas averages 16.8 yards per catch and leads the Broncos with 30 catches for 505 yards, stats that rank him third and 11th in the NFL, respectively. His nine-catch, 180-yard performance against the Patriots was his second consecutive game over the 100-yard mark and third this season.
Given the extra day to prepare, it could just be cautionary, and their availability to practice Friday will be more indicative of their status for Monday's game.
Linebacker Keith Brooking (concussion) was also limited Thursday, and fullback Chris Gronkowski (thigh) cornerback Chris Harris (ankle), right guard Chris Kuper (forearm) and wide receiver Matt Willis (non-injury related) all are on the injury report but practiced fully.
