Vaughn isn't starting Thursday against the Tigers due to an illness, Scot Gregor of the Chicago Daily Herald reports.

EDGE Analysis

Vaughn started in the last six games, but manager Tony La Russa revealed prior to the game that the 24-year-old is out of the lineup since he's feeling under the weather. Vaughn should be considered day-to-day as long as he doesn't test positive for COVID-19.
