"It sucks having to sit there and watch when it wasn't the most painful thing I've ever dealt with. It really wasn't ... it was just a lack of being able to do my job," Carr said. "And so that was the most frustrating part, because I couldn't just play through it, you know? I just literally couldn't do it. ... It's been the most frustrating injury I've ever had, besides breaking my ankle and not being able to play in the playoffs that year. ... because there's literally nothing that I could do, but wait and just let it heal."
