Anderson suffered a high ankle sprain in Tuesday's loss to the Red Sox and is expected to be placed on the IL before Chicago's weekend series against Minnesota. He said he felt "a lot better" on Wednesday, just after Chicago rallied for an 8-7 win over the Red Sox.
"I just planted wrong," Anderson said. "I kind of felt a little pop. It kind of scared me a little bit."
The team said Anderson was diagnosed with a high ankle sprain, but manager Rick Renteria said he had not seen the results of an MRI taken on Wednesday. X-rays on Tuesday were negative; Anderson was walking in flip flops with a pronounced limp after the game, then he put on a walking boot to leave the ballpark.
"Everything will be announced on Friday," Renteria said. "I don't have a timetable for you."
Less than two hours later, Moncada limped off the field in the first inning after being hit on his right knee by a pitch from Red Sox ace Chris Sale. The White Sox announced he has a bruised knee.
Moncada initially tried to stay in the game but ultimately was replaced by Yolmer Sanchez after struggling to run the bases. The White Sox have not announced an official diagnosis for Moncada's injury.
Anderson, 26, was enjoying a breakout season, batting .317 with 11 home runs, 37 RBIs and 15 stolen bases. Leury Garcia replaced Anderson at shortstop in Wednesday afternoon's game.
Moncada, 24, is batting .299 with 13 homers and 42 RBIs.
