Urias was officially optioned to Triple-A Oklahoma City on Thursday, Andy McCullough of the Los Angeles Times reports.
It had previously been reported that Urias would not be on the Opening Day roster, but the Dodgers made the move official during their final round of cuts Thursday. The Dodgers will reportedly limit Urias' innings in the early portion of the season in an effort to keep him fresh down the stretch. He'll likely be back with the major-league club later this spring or early in the summer.
