Kelvin was injured in practice Tuesday. It was a hamstring injury and he was carted off the field according to the article. This is very concerning, seeing as Hayden is a very talented corner (the best on the roster at that), and the defense was very different while he was out last year. Hopefully its just a minor strain and he will be back very soon, but the injuries are not looking good already in the season. Everyone better be healthy by week one because this team has the talent to win the big one this year.
