The Kansas City Royals placed third baseman Mike Moustakas on the 15-day disabled list Thursday with a torn ACL in his right knee that could end his season.
Outfielder Brett Eibner was recalled from Triple-A Omaha to take his roster spot.
Moustakas injured the knee on Sunday during a collision with outfielder Alex Gordon while trying to catch a foul popup in a game against the Chicago White Sox. He had missed the last three games before going on the DL.
Gordon broke a bone in his right wrist on the same play and was placed on the DL on Monday. He could be sidelined for three to four weeks.
Moustakas had just returned from a stay on the 15-day disabled list after recovering from a small fracture in his left thumb. He is hitting .240 with seven home runs and 13 RBIs this season.
