Is this a line from Friends?
As I understand it, it's an American football term, and in this example it means 'allow himself to be tackled'.Ross : Right, but, it is just me and the baby, so I'm thinkin' they can take us. And so I uh, hah-hah, I just heave it down field.
Chandler : What are you crazy? That's a baby!
Joey : He should take the sack?
If it's not from Friends, then I may be wrong.
