Graham Mertz’s second test to confirm his COVID-19 diagnosis is back and it’s not good news for the Wisconsin quarterback.

As first reported by CBSSports.com’s Dennis Dodd, a PCR nasal test confirmed the positive result of the daily rapid antigen test taken over the weekend. second test to confirm Wisconsin quarterback Graham Mertz has reportedly tested positive for COVID-19. It means Mertz will not be allowed to play in a game for 21 days and will miss at least two games — Nebraska and Purdue. During that time, Mertz will also undergo extensive heart testing to try and determine any long-term issues that could arrive from having COVID-19. Once he tests negative for the virus and gets cardiac clearance by an appointed cardiologist, he can return to practice.

With Mertz reportedly testing positive on Sept. 24, it’s possible he would be able to return in time for the Michigan game on Nov. 14, as that would be day No. 22 since the first positive.

The news of the positive test comes days after Mertz lit the college football world on fire with his starting debut. He completed 20 of 21 passes for 248 yards and five touchdowns. His 95.2 percent completion percentage set the school record and he tied the school record with 17 straight completions at one point.

Making the news worse is that his backup, Chase Wolf, also reportedly tested positive. His second test to confirm has not yet been reported on.

With both Mertz and Wolf out, and normal starter Jack Coan still recovering from foot surgery, Wisconsin will likely turn to fourth-string quarterback Danny Vanden Boom.

The ninth-ranked Badgers (1-0) travel to Nebraska (0-1) on Saturday to face the Cornhuskers.
