Floyd left Sunday's game against the Seattle Mariners after two innings due to discomfort in his throwing elbow. He was on the 15-day disabled list in July because of tendinitis in the same elbow. Floyd said he experienced a similar feeling Sunday to the discomfort he felt in July.
"I don't have everything, but everything structurally seems to be all right," Ventura said prior to Monday's game with the Baltimore Orioles. "He still has something in there that they're checking on. Nothing that would put him out for the rest of the year.
"I think the part that concerns you is he's already had a DL stint for the same thing. Once he starts talking about not feeling right, you just don't like to send him out there or even him take his next start. I don't know. I just know it concerns you enough when you're dealing with a guy's future, his health and all that."
Floyd is 9-9 with a 4.55 ERA in 24 starts this season.
Floyd will miss his next start and Ventura has altered his rotation due to the upcoming series with the Detroit Tigers, who trail the White Sox by 2½ games in the American League Central. Ventura said Hector Santiago, Phil Humber or someone else would start against the Orioles on Wednesday, and Jake Peavy would start against the Tigers on Friday. Peavy was previously scheduled to start Wednesday.
"Just gives (Peavy) an extra couple days to line up against the guys we're going against and go from there," Ventura said. "You want your guys you're counting on, your best guys, going and take your best shot."
The White Sox's rotation has evolved since the beginning of the season. Opening Day pitcher John Danks had season-ending surgery on his throwing shoulder. Humber, who threw a perfect game this season, was demoted to the bullpen. Jose Quintana began the season in the minors and has now made 16 starts in the majors. The White Sox also traded for Francisco Liriano, who started on Monday. Floyd, Peavy and Chris Sale all began the season in the rotation and have remained in it for most of the year.
