Chicago White Sox ace Chris Sale was a late scratch from his start Saturday against the Detroit Tigers, speculating trade rumors.

Instead, it was because he was involved in what the team says was a “clubhouse incident.”

“Chris Sale has been scratched from tonight’s scheduled start and sent home from the ballpark by the White Sox due to a clubhouse incident before the game,” White Sox senior vice president/general manager Rick Hahn said in a statement. “The incident, which was non-physical in nature, currently is under further investigation by the club.

“The White Sox will have no additional comment until the investigation is completed.”

The White Sox had expected to be in contention for the postseason, but have faded (46-50), making Sale expendable.

The Texas Rangers appear to be the front-runners to land the All-Star, but the asking price is said to be very high. The Boston Red Sox have also shown interest.

If he were traded the Rangers, he would join a formidable rotation that includes Cole Hamels and Yu Darvish.

He has a very team-friendly contract and is under contract through the 2017 season. The club has options in 2018 and 2019 that likely will be exercised. If so, he would earn $ 38 million between 2017-19.

The five-time All-Star leads the American League with 14 wins and has a 3.18 ERA and is 71-43 with a 2.97 ERA for his career.

This isn’t Sale’s first run-in with the organization. During spring training, Sale was openly critical of team president Ken Williams after he told Adam LaRoche his son was no longer allowed in the clubhouse. LaRoche decided to retire.
