For people who wear glasses, you know of one negative effect from having to wear masks during the COVID-19 pandemic — they can fog up your lenses. And nobody likes not being able to see.

That became a problem for Kentucky offensive coordinator Eddie Gran during Saturday’s win over Tennessee. In fact, it even impacted one of the Wildcats’ early plays on offense.

During his Monday press conference, Kentucky head coach Mark Stoops shared that Gran’s glasses getting fogged up caused his team to run the wrong play on its opening drive against the Vols.

“We can chuckle about it now, but I promise you, it wasn’t funny at the time,” Stoops told the media. “We had a miscommunication on, I want to say, the second play of the game when Eddie’s glasses — he was so hyped up, he had that mask on and his glasses got all fogged up and he called a formation wrong. He called a play wrong. He felt so bad because he could not see his play chart, so that put us in 3rd-and-long early.”

If Stoops remembered correctly, then the play was a 2-yard loss on a rush by Asim Rose. The Wildcats’ drive ended with them having to punt it away after they allowed a sack on third down.

It didn’t end up mattering, though, as Kentucky went on to win 34-7.

The Wildcats will be looking to keep that momentum going when they travel to play Missouri on Saturday at 4 p.m. ET on SEC Network.
