Whether it's fair or not, injuries can drop a player's stock in training camp just as fast as poor play can.
Unfortunately for Colin McCarthy, his nagging injuries are forcing him to be overshadowed by Moise Fokou, who was one of several big free-agent signings this offseason.
Per The Associated Press' Teresa M. Walker, McCarthy could easily end up losing his starting role at middle linebacker in Week 1 if he continues to miss time due to injuries.
His latest injury is an aggravated hamstring that is forcing him to miss more vital time and that will also keep him out of the preseason opener against the Redskins.
Even though McCarthy has already proven himself in the past to be an outstanding leader for the defense, he still has to be out there performing in training camp.
Now it's obviously not the end of the world for McCarthy. He could end up coming back looking better than ever in the final three games of the preseason and reinforce that he's hands-down the top option at middle linebacker for the Titans.
It's hard to do that when you're on the sidelines watching, though.
You have to remember that the Titans are full of position battles right now, and McCarthy isn't exempt from that. Until he can consistently stay on the field and remind coaches how good he really is, Fokou is going to keep inching closer to winning that starting role in Week 1.
