Rivera (wrist) will shift his rehab assignment from Double-A Northwest Arkansas to Triple-A Omaha on Tuesday.
Rivera played four games at Double-A, going 4-for-15 with a pair of walks. He'll likely start in multiple contests at Triple-A before the Royals presumably reevaluate him for a return from the 10-day injured list ahead of their weekend series in St. Louis. Once activated, Rivera will likely be limited to a backup role in the Kansas City infield, but he could also be optioned back to Omaha.
