Cobb said it accurately when he describes how he fell. While trying to haul in a pass, he fell hard flat on his back. 

The hit took a pretty serious toll on the wideout.

“I felt fine, I got up from the catch and started walking back to the huddle and it got harder and harder for me to breathe,” he said. “Then it felt like I was going to throw up. I was choking. I was choking on something and then next thing I know I was spitting up blood.”
