Wisconsin quarterback Graham Mertz has tested positive for COVID-19 a second time, confirming his first positive result, according to CBS Sports' Dennis Dodd and Barrett Sallee.
Mertz will miss Saturday's game against Nebraska and sit out at least 21 days under the Big Ten's COVID-19 protocol. Reports surfaced on Sunday that he tested positive on Saturday–one day after the Badgers' opening-night win over Illinois.
Mertz reportedly underwent a polymerase chain reaction (PCR) test to determine whether the first result was a false positive.
The Badgers took another hit on Monday when third-string quarterback Chase Wolf reportedly missed practice and also tested positive for COVID-19.
