The Royals placed Kolek (personal) on the Family Medical Emergency List on Saturday.
Kolek's next start is tentatively slated for next week on the road against the Mets, though it's unclear whether he'll be with the team at that time. He took the loss in his last start against the Rays on Thursday, when he allowed three runs on four hits and one walk across two innings without recording a strikeout. Prior to that outing, Kolek spent some time on the paternity list and then the family medical emergency list before rejoining the team Thursday. The Royals recalled right-hander Jose Cuas from Triple-A Omaha in a corresponding move.
