Quentin returns to Chicago for treatment

Quentin returns to Chicago for treatment

TORONTO -- White Sox left fielder Carlos Quentin headed back to Chicago on Sunday night to receive treatment on his injured left foot.

After spending time in the trainer's room and taking soft tosses from hitting coach Greg Walker before Sunday's game against the Blue Jays, Quentin decided that he wasn't fit to help the Sox and elected to return to the Windy City.

White Sox interim manager Joey Cora said that Quentin -- who is set to undergo treatment on his foot Monday -- could rejoin the White Sox on Tuesday for the beginning of their six-game homestand.

Originally, Quentin had been bothered by a sore left heel that kept him from the starting lineup twice this week. After getting a cortisone shot earlier in the week, Quentin is now being bothered by pain in the middle of his foot.

"The spot where the cortisone shot was, it worked in that particular area, but [the soreness] moved to some other area." said Cora. "[The trainers] don't think it's something really bad. It's just a bad spot, I guess."

Quentin is hitting .229 with eight home runs and 18 RBIs in 33 games for the White Sox this year.
