Derek Carr has been busy on Twitter the last few days, and he turned his attention to the hosts of ESPN's First Take on Wednesday afternoon.

We'll let Carr's tweets speak for themselves. Here are a series of tweets directed at hosts Stephen A. Smith and Max Kellerman:

😂it’s because I blocked them both for talking trash about our team. Those 2 clowns don’t know anything about this game. Would love to actually sit and break down film with these two on tv just to show their viewers how incompetent (lacking qualification) they are about our game. — Derek Carr (@derekcarrqb) January 23, 2019

@ufc @danawhite hey how do I challenge a couple of these clowns on tv to a fight? I think we should start a business together. Where pro athletes can challenge some of these people to an octagon fight until they give us an answer.... You don’t know me... stop lying. — Derek Carr (@derekcarrqb) January 23, 2019

Yes..say what you want but don’t question somebodies character as a man if you don’t know them. Our job as NFL athletes is to try and leave the game better for the next generations. So let’s start an octagon business to give some accountability to these kinds of people. 😉😂👊🏼 — Derek Carr (@derekcarrqb) January 23, 2019

Yes, that is Carr tweeting at UFC owner Dana White asking him to set up a fight in an octagon.

Where did this outburst come from? It stems from Kellerman's comments regarding Jon Gruden's praise of NFL draft prospect Kyler Murray.

Kellerman had this to say when addressing what Gruden said:

"You can see where quarterbacks don't want it, and Carr didn't want it. And I think Gruden knows they have to move on. The question is, can they get anything for him? Is he a placeholder until they find the next guy? How long will it take to develop the next guy? And Kyler Murray, if you can grab him in the draft, hell yeah."

So you can see why Carr is so angry. Kellerman is questioning Carr's desire.

This isn't the first time Kellerman has taken a shot at Carr. Back in October, after a report surfaced that Carr had lost the support of his teammates because of how he reacts to injuries, Kellerman said he had lost confidence in Carr.

"Under pressure, he doesn't perform well," Kellerman said.

Anyway, we'd pay good money to see Carr get into the octagon with Kellerman. Let's hope White can set that up.
