The Panthers resumed their summer school OTAs Monday, and rookie tackle Jeff Otah practiced with the team for the first time.  Otah, one of the Panther’s two first-round draft choices, missed the team’s minicamp and the first week of summer school with a high ankle sprain.  Otah suffered the injury prior to his senior season at Pittsburgh.  Running back Jonathan Stewart, Carolina’s other first-round pick, is not at the OTAs because classes were still in session.  Stewart is also recovering from a toe injury.
