After weeks of momentum building towards having a college football season and kickoff beginning on time, there’s now some growing concerns about whether the sport can be played this fall following a handful of outbreaks on campuses.

On Monday, ESPN college football analyst Laura Rutledge says that, after a few schools have reported high numbers of positive tests, there are increased concerns among student-athletes. The worry is the highest it has been in weeks.

“I’m hearing there are many more cases we don’t know about,” Rutledge said, according to 247Sports. “That’s to be expected, but I think this is more widespread and a larger volume of cases than people realize in college football. I’m getting a sense of concern from players that wasn’t there just a couple weeks ago. There’s actually some players who are trying to figure out how they could write a letter to the NCAA expressing their concerns. But here’s the problem — they want to remain anonymous because they’re concerned that all of the sudden maybe a university would say, ‘Hey, if you’re that worried about this, just quarantine and don’t play.

“It’s a double-edged sword that while they’re worried about their health, they still really want to play football and want to be given a fair chance to compete. This will continue to be very complicated and I think you’ll see a lot more school have to enforce quarantine. And still, all of the [athletic directors] and coaches I’ve spoken to are planning on starting college football on time.”

Over the last week, several campuses have seen numerous student-athletes test positive for the COVID-19 virus. Kansas State halted voluntary workouts after 14 student-athletes tested positive. Clemson reported 25 players and staff members provided positive tests. LSU has 30 players either testing positive or in quarantine at the moment.

With so many cases as student-athletes return to campus, the concern about the season has grown.
