McCoy suffered a hamstring injury in practice on Aug. 18. The source tells Anderson that McCoy's MRI showed, what was described internally, as a "small tear," adding: "They say it tore in a spot where it couldn't have been any better for us. It tore in a spot that is kind of high up, surrounded by stronger muscles in the glutes and things like that."
According to the source, McCoy is not at full speed in practice, but is doing rehab work including light footwork, agility and cardio conditioning, but there is concern he won't be in great "football shape."
"It's way too early to say whether [McCoy] will play or not. He is doing a little bit more every day. But hell yes, I'm concerned about that," the source said. "I can't say for sure he's going to be with us Week 1. I can't say that at all. It will take everything we got just to get him ready for game day, and then [when] we get to game day [there's] no way he can be in great football shape. So I think he will be on a pitch count, I think at the very best.
"I mean if he came around and just started feeling really, really, good heaven knows, but [we] have to look at all the contingency plans: putting him on a pitch count possibly, or, he's not out there at all and we got to go without him and get the other guys ready-you just don't know."
The source emphasized that the team is "still game planning for him to be ready. We're hoping he will be ready, but I can't sit here and tell you that he will be ready."
The source added that if McCoy is not 100 percent, "I would recommend that he doesn't play because [we] need him for the rest of the year. [We] don't need him at 75 percent and risk losing him down the line."
"You know he is a Ferrari and for him to be hitting on all cylinders, that thing has got to be right," the source told Anderson.
