Trevor Lawrence just wants to play. All he can do for now is watch.

The star quarterback of the United States' top-ranked college football team has joined millions of victims of the coronavirus pandemic, becoming another stark reminder of just how tenuous this season really is.

A positive test last week forced Lawrence to sit out Clemson's 34-28 victory over Boston College on Saturday.

More stunningly, he won't be able to play this weekend in one of the biggest games of the season against No 4 Notre Dame because of Atlantic Coast Conference protocols.

"My symptoms have been fairly mild while I'm following the protocol from Clemson and the ACC," Lawrence wrote on Twitter. "The only thing that hurts is missing an opportunity to be with my teammates this weekend and play the game I love."

It was a cruel twist of fate for a player who energized the movement to have a season when he urged those in charge to "Let Us Play".

"He's the best player in college football," Notre Dame coach Brian Kelly said after his team defeated Georgia Tech.

"But the virus is indiscriminate. It doesn't care. The virus is going to do what the virus does."

While it's probably a stretch to say there wouldn't have been a season without Lawrence's pleas－seriously, do we think athletic departments were going to pass up all that television money?－it was still a powerful message coming from a player who will likely be the No 1 pick in next year's NFL draft.

No one should blame Lawrence－even now, when he's hopefully recovering with no long-term health issues－for his passionate desire to play one more season with the Tigers.

Lawrence certainly didn't need a third year to improve his draft stock after leading the Tigers to the national championship as a freshman and another trip to the title game last season. But he really seems to enjoy the college game and simply wanted another crack at a trophy with the Tigers.

Whether it was the right stand to take will likely be debated for years to come as frightening news just keeps on coming from a virus that couldn't care less who wins on Saturdays.

The United States' total number of coronavirus cases stands at over 9 million. The tally of new cases keeps climbing－especially in the Midwest, where state after state keeps reporting new highs for daily infections.

Those states are essentially the footprint of the Big Ten, which initially chose to hold off playing.

Many observers still contend that would have been the proper call, especially now. But when three other major conferences decided to take the field, the Big Ten (as well as the Pac-12) buckled to recruiting and financial pressures to hold an abbreviated season that began late last month.

It was a horrific bit of timing, coming right in the midst of the worst numbers yet for a worldwide health crisis that shows no signs of abating.

No 9 Wisconsin was forced to cancel its game on Saturday at Nebraska and pause team activities for at least a week after at least 22 people in the program－including coach Paul Chryst－tested positive for COVID-19.

"We're still having additions in our cases, and that's something we've got to get our arms around and control it," athletic director Barry Alvarez said on ESPN's College GameDay.

The bad news kept on coming with Illinois－which lost its opener to Wisconsin－announcing that senior starting quarterback Brandon Peters and redshirt freshman tight end Griffin Moore wouldn't be able to play Saturday against Purdue after positive tests.

Peters' backup, Isaiah Washington, also missed the game due to contact-tracing protocols. In all, 12 Illinois players were scratched, including kicker James McCourt.

Forced to go with its fourth-string quarterback, Illinois lost to Purdue 31-24. Under Big Ten rules, Peters and Moore will have to sit for 21 days－missing three games in an eight-game regular season－before they are eligible to return.

While Chryst understood the decision to postpone Wisconsin's game, he was kicking himself for being part of an outbreak so early into a season that had taken so long to get off the ground.

"When you have a hand in it," he said, "that's where there's disappointment."

It's not known when the Badgers will return to the field.

There were reports that quarterback Graham Mertz has tested positive twice－which would require him to sit out at least 21 days－and backup quarterback Chase Wolf had tested positive at least once. Wisconsin has only one other quarterback on scholarship.

Lawrence will miss the game at Notre Dame under ACC guidelines that require him to sit out at least 10 days.

"I hate that I can't be there, but I'll be watching from isolation and pulling for our guys while I wait for the opportunity to rejoin the team," Lawrence said.
