Cardinals running back Andre Ellington was not a participant in practice on Friday, as he continues to rest his injured left foot, the team announced. He's in danger of missing Week 1 against Chargers because of the issue.

Ellington underwent an MRI on Thursday and is expected to visit a local foot specialist to examine the extent of the injury. The initial reports indicate that he's dealing with a muscular injury. The team is still waiting on the results of his exam.
