SPARTANBURG, S.C. – There was no beating the heat Monday.

Despite practicing in the morning, the Panthers faced the highest heat index of training camp so far, topping out at 106 degrees even with the air temperature not quire reaching 90.

Head coach Ron Rivera opted to cut the final period in practice in half and instead go through those plays during the team's evening walkthrough.

"We had a situation where we had three guys cramp in a row, so I just felt like it was better safe than sorry," Rivera said. "We encouraged guys to go under the tent, encouraged guys to stay on the sideline in the shade."

-Left tackle Matt Kalil missed out on the heat all together, sitting out practice.

"It was pretty much – well I don't want to call it a vet day – but it pretty much was a vet day," Rivera said. "We just wanted to give him a little time off and get him ready for Thursday."
