Soler has returned home to attend to a personal matter and will not be recalled until a later date, according to Jeffrey Flanagan of MLB.com.
The report did not include any estimate of how long Soler will be away from the team, but it does indicate he will join the Royals' major-league squad at some point before September comes to a close. Soler posted an impressive .932 OPS over 71 games with Triple-A Omaha this season, so he could see a healthy amount of playing time when he returns so the Royals can gauge if his power carries over to the top level.
