CHICAGO -- Chicago White Sox outfielder Eloy Jimenez has a sprained right foot, likely sidelining the slugger for a pivotal season-ending series against the crosstown Cubs.

The White Sox had dropped a season-high five in a row heading into the weekend set, falling out of first place in the AL Central. They are hoping to get back on track heading into their playoff appearance since 2008, but the health of Jimenez is a concern.

Jimenez, who is batting .296 with 14 homers and 41 RBI, was injured sliding across home in the seventh inning of Chicago's 5-4 loss at Cleveland on Thursday. Manager Rick Renteria said the 23-year-old left fielder will need "to be off his feet" for a few days.

"There's inflammation in there, and they want to calm it down" Renteria said. "We'll know more in a few days."

The White Sox trailed the first-place Twins by a game heading into the series with the Cubs. They are just one game ahead of the third-place Indians. The AL postseason begins on Tuesday.
