The 25-year-old Castellanos, acquired at the Trade Deadline from St. Louis in exchange for shortstop Rafael Furcal, was batting .379 with three homers, 13 runs scored, four steals and a 1.289 OPS in eight games when he suffered the injury. He was replaced on the Salt River roster by another Dodgers Minor Leaguer, Brian Cavazos-Galvez.
Castellanos, a right-handed-hitting right fielder, hit a combined .320 with 23 homers and 85 RBIs in 2011 at Double-A for the two franchises. The Dodgers have considered moving him to first base.
Castellanos is expected by the club to be ready for Spring Training with no restrictions.
