“I will not, cannot and should not therefore comment about anything dealing with our testing and coronavirus,” Chryst said Monday.
The Milwaukee Journal-Sentinel and Wisconsin State Journal both reported that Mertz had tested positive.
The Journal-Sentinel reported Mertz’s positive test came Saturday, one day after the Badgers’ 45-7 season-opening home victory over Illinois.
If that second test confirms a positive result, the athlete can’t play again for at least 21 days.
Chryst said he has no problem with the Big Ten’s 21-day policy, which is more stringent than those of most conferences regarding players who test positive.
