Thomas has inflammation in his ankle
The White Sox learned Friday they will lose Thomas, one day after fellow slugger Magglio Ordonez came off the disabled list. This will be Thomas' fourth trip to the DL for ankle tendenitis.
"I worry about him," White Sox manager Ozzie Guillen said. "I don't want him to get worse. Hopefully, he can come back ready to play."
The Chicago Tribune on Saturday speculated that Guillen shouldn't get his hopes up too high. The Tribune noted that because Thomas dislikes playing unless he can perform at his optimum, he may choose surgery now rather than waiting until after the season.
Ordonez missed 36 games after tearing cartilage in his left knee. He had surgery on June 5.
The White Sox will recall outfielder Joe Borchard from Triple-A Charlotte.
Thomas missed the past two games and was unable to start at first base during the interleague series against the Chicago Cubs last week. He suffered the injury June 17 at Florida and aggravated it again last week against the Twins.
The two-time AL MVP was told to rest for two to three weeks by team podiatrist Dr. Lowell Scott Weil. Thomas will wear a special brace on his ankle.
Thomas went 4-for-34 in his last 12 games, going hitless in his last nine at-bats. He's hitting .271 with 18 homers and 49 RBI this season.
Borchard was hitting .267 for Charlotte with 16 homers and 48 RBI. He batted .184 for the White Sox in 15 games last season.
