MacIver (shoulder) has gone 4-for-11 with two doubles, three walks, four runs, three RBI and three stolen bases over four games in the Arizona Complex League since being assigned to the Rockies' rookie-level affiliate June 5.

MacIver is expected to miss the first 6-to-8 weeks of Triple-A Albuquerque's season after he recently received an anti-inflammatory injection in his right shoulder, Thomas Harding of MLB.com reports.
