White Sox place Kopech on Bereavement List

Michael Kopech will not be available to the White Sox for up to a week, but not necessarily because of the hamstring injury he suffered in Wednesday's loss to the Cardinals.

Before Thursday night's game against the Orioles, the Sox placed Kopech on the Bereavement List. Under MLB rules, Kopech has to stay on the list for at least three days but no more than seven.

Kopech hurt his hamstring on his final pitch in relief. The 25-year-old righty fell to the ground in pain and limped off the field.

The White Sox still aren't 100 percent sure how serious the injury is, but they're hopeful.

"You've got to give it 24, 48 hours to see," manager Tony La Russa said. "We have our fingers crossed it's not something that's going to last very long. We probably don't expect to know anything more until tomorrow. Ask the doctors, but I know it was something that gives us an optimistic belief that it's going to be something we can take care of."
