What does "got carried off the field" imply or mean in this sentence?

Question

I couldn't get the implication or metaphor of the phrase in the following sentence; is it a slang?

The context is :

Bruce Banner, the Hulk, got under the mind control of Wanda, and he went rogue, causing great damage to the civilians. The whole team is a mess now.

Here is the sentence:

He was talking to Maria Hill, who was on the dashboard screen. “The news is loving you guys,” she said. “Nobody else is. There’s been no official call for Banner’s arrest, but it’s in the air.”

“The Stark Relief Foundation—” Tony began, but she was ahead of him.

“Already on the scene. How’s the team?”

“Everyone’s . . .” Tony had meant to say something reassuring, but he couldn’t make it happen. “We took a hit. We’ll shake it off.”

“People find out the Avengers got carried off the field, there’s going to be panic,” Hill said. “And that’s from the people that like you.”

“Recommendation,” Tony said.

“Stay in stealth mode and stay away from here.”

“So run and hide.”

“Until we can find Ultron,” Hill said, “I don’t have a lot else to offer.”

Answer 1

In sporting and military battles, when you are injured you are literally carried off the field. In the example it's not clear whether they were actually injured, or whether the speaker is worried that they might be.

Note that the grammar in your example is a kind of abbreviated style common to spoken military and police.

The following examples have the same meaning.

• Example: People find out X, there's going to be Y
• Fuller: If people find out X, there's going to be Y
• Fullest: If people find out X, then there's going to be Y
