Thomas didn't practice Wednesday due to a foot injury.
Thomas left the Saints' Week 3 loss to the Panthers with what the Saints described as a foot injury, but Ian Rapoport of NFL Network reported Monday that the wide receiver instead was dealing with a toe issue and was slated for additional testing on the appendage. The Saints are still labeling the health concern as a foot injury in the meantime, and Thomas will have opportunities to get on the practice field Thursday and Friday. After that, the team may provide some clarity on his odds to play Sunday against the Vikings in London.
