Okoye (ankle) left practice early on Sunday after injuring his arm, Sportsday.com reports.
Okoye was already dealing with an ankle injury that he was practicing with prior to injuring his arm. The severity of his arm injury is not known, leaving him without a timetable to return. He'll join the long list of Cowboys defensive lineman unable to practice. Look for Jack Crawford to see an increase in reps while Okoye is out.
