White Sox manager Pedro Grifol informed the media Thursday that Eloy Jimenez will be out for an "extended period of time" with a hamstring injury he suffered in a game against the Toronto Blue Jays on Tuesday.
"Exactly how much time, who knows," Grifol said.
The White Sox initially placed him on the 10-day injured list with a strained hamstring, but Thursday's update indicates he won't be back for some time.

Jimenez suffered the injury rounding third base, trying to score from second on a fifth-inning single by Corey Julks.
This is the second IL stint of the season for Jimenez, who missed 12 games in April with a left adductor strain.
On the season, he'd been slashing .231/.288/.381 with five home runs and 12 RBI.
