Yes, they've known. Easily could have had an MRI a lot earlier. If your best player, and someone you're considering giving $40+ million dollars a year to has "back tightness", you don't sit there and twiddle your thumbs for weeks/months. You get that MRI pretty darn soon.
And, if (a big question mark) it's football related, the responsibility to get it taken care of lies first with the Cowboys.
It already was taken care of by the Cowboys. He had the MRI, it came back clean, and the team cleared him. Objectively, there is no issue with his back. Micah is relying on subjective metrics to avoid playing. Try getting worker's comp with a subjective "I hurt my back on the job. Everything came back clean with the tests, but my back hurts. Can't work. Pay me anyway."
Micah is the one making it an issue by running off for a second opinion.
And let’s be real here: if his back were actually “injured,” he could sit out and still collect a paycheck. If it’s not injured, he has two choices—play and get paid, or sit out and forfeit game checks. He doesn’t want to play, plain and simple.
So what we’re seeing is this: Micah spent the entire offseason not making a fuss about his back. No urgency regarding getting it checked out. He practiced some, and then sat out all of training camp. Then suddenly points to a “back injury" when the contract isn't getting done. He finally gets an MRI, it’s clean, the doctors clear him, and instead of practicing, he refuses and seeks another opinion. Why? Because he doesn’t want to step on the field.
And here’s the kicker, this isn’t new. His agent pulled the exact same stunt with Jalen Ramsey to get him out of Jacksonville. Total coincidence, right? And let’s not forget Micah already bailed once before at Penn State to protect his draft stock and his pocketbook.
Looks less like a medical problem and more like a pattern.
