Rick Renteria woke up Monday with "a slight cough and nasal congestion" and will be kept away from the Chicago White Sox pending the results of medical tests.

Joe McEwing will manage the White Sox until the team learns more about Renteria's condition. Monday's opener of a three-game set at the Cleveland Indians was postponed by rain and will be made up Tuesday as part of a doubleheader.

"Out of an abundance of caution, Ricky will remain at the team hotel and not manage until we receive confirmation of today's test result," Rick Hahn said.
