Chicago White Sox All-Star shortstop Tim Anderson is expected to miss six weeks because of a tear in the middle of his left hand suffered in a game last weekend.

The playoff-contending White Sox made the announcement Tuesday after losing to Kansas City 4-2 in the first game of a doubleheader. The 29-year-old Anderson, an All-Star the last two seasons, is batting .301.

Anderson will have surgery on Thursday in Chicago. He was hurt Saturday on a check swing in his last at-bat in a win at Texas.

“Huge blow. He’s one of our All-Stars and one of our leaders,” White Sox pitcher Lance Lynn said.

If Anderson returned in six weeks, he’d rejoin the club with two weeks left in the regular season.
