The running back picked up a neck injury last Sunday, and will seek a second opinion after initial tests suggested a spinal stenosis, where the spinal canal is abnormally narrowed.
The 22-year-old told reporters: "Perfect. Nothing. No pain, all motion, all strength, there's nothing wrong with me except the X-ray. They want to be cautious about it. That's the most frustrating part is feeling like I do, feeling healthy.
"Everything is ready with me. I feel perfectly fine but on the X-rays, one vertebra is closer to my spinal cord. That's a precaution thing. Of course, I feel like none of my spine is lined up perfectly, especially after years playing football. We've all got something here or there. They said they want to be cautious and check it out further.
"Best case, I'll be back after the second opinion. That's what I'm hoping and praying for, because I feel perfectly fine. It really doesn't make sense to me right now. People say, 'Oh, but it's the neck'. But I feel like I'm fine. I'm willing to go out there and sacrifice and play with my team, this is what I love. That's my choice."
