So, what is it? It's injury or it's not as much room to run or it's both. His health has been a factor, no doubt. He's working hard to become healthier. That's important. That's a hip flexor. That's a muscle injury, and it's hard to predict exactly what impact that has, but you've got to assume it's had an impact."
