Both Jon Gruden and Derek Carr downplayed a heated conversation on the sidelines during the first half of Sunday's 23-21 win over the Arizona Cardinals.

It wasn't the first such exchange for the Oakland Raiders and it likely won't be the last.

Gruden got on Carr after he missed an open receiver down the right sideline on a third-down pass.

"That's the first time you've seen it," Gruden said, "but it isn't the first time it's happened. We're both competitors. We're competing hard there. We had a man-to-man situation and he went for the big play.

"We had a mild disagreement. But you know what, that's part of this business. We're going to have times where we clash a little bit but we're also very supportive of one another. I'm really proud of him. He's been through a lot this year, and I'm glad he's our quarterback."

Gruden is notoriously hard on quarterbacks.

"We're both very fiery -- a lot of people don't see that in me, all the time -- we're both competitive," Carr said. "A minor disagreement on something and the beautiful thing is, when we do that, it's not a demeaning thing or pointing a finger. We're both yelling the same kind of thing, almost: 'Let's fix it!'

"Everything's good, I promise."
