According to the Arizona Republic, Chris Wells sprained his right ankle in practice yesterday.
No need to worry about his ankle. He is tough and he will be back on the field next week some time. In the meantime, he gets to study, study, study. WIth nothing else to do, but study the playbook and get to know his team, he should be prepared to concentrate on getting the edge on Hightower for the starting role in Arizona. You can still draft Beanie in late rounds of your fantasy football draft.
