Braised cross cut short ribs on the grill?

[FishEER]

Back or anyone, have you ever grilled cross cut short ribs? They're pretty thin so I'll sear them quickly then move to indirect heat for a few minutes. I'm concerned they'll be tough though? Thought about putting them in a traditional wet rub this evening then grilling them tomorrow. I think tenderizing is a must, am I missing something?

Thanks for the help guys!

Even though they are thin I would think the cook would take more than a few minutes. I would suggest keeping them very wet and cook on indirect heat for a fairly long time...
