The Kansas City Royals placed third baseman Mike Moustakas on the 15-day disabled list Thursday with a torn anterior cruciate ligament in his right knee.

Such injuries usually sideline a player for a long period.

Moustakas and leftfielder Alex Gordon collided Sunday while chasing a fly ball in Chicago. Gordon went on the disabled list Monday with a right wrist fracture.

Moustakas did not play in the next three games at Minnesota and was checked out by team physicians upon returning to Kansas City for a seven-game home stand beginning Thursday against the Chicago White Sox.

The Chicago White Sox game at the Kansas City Royals was postponed because of rain on Thursday night.

No makeup date was announced, but it will not be rescheduled as part of this series.

It was the second rainout this season for the Royals.
