The Dolphins selected Ja'Wuan James to be the team's starting right tackle in 2014 but before that was to happen there was supposed to be a competition between James and veteran Jason Fox.
That competition will not necessarily start immediately in the offseason conditioning and OTAs because Fox is nursing a leg injury.
Fox was wearing a walking boot on Saturday and obviously is not doing any running in the offseason program. But a source characterized the injury as "very minor" and added "He is fine."
Another source said Fox has been in the boot for some time and it will be coming off soon.
Fox has been plagued by injuries during his career. He was inactive early in 2011 and was eventually placed on injured reserve. In 2013, Fox won the starting right tackle job in Detroit but suffered a groin injury in the opener and lost his job.
