Young left the Twins last Friday before the start of a four-game series at the New York Yankees to attend to his mother, Bonnie, and was placed on the family medical emergency list.
Twins manager Ron Gardenhire said Tuesday that Young will miss the three-game series against the Chicago White Sox and not be back until Friday at the earliest. Services are planned later in the week in Vicksburg, Miss.
Young is hitting .277 with one home run and 14 RBIs.
Young's brother Dmitri Young is with the Nationals, but has been on the disabled list all season.
