I think Mark's quotes from tonight's press conference demonstrate that the missed practice time won't be a big deal:
On what missing a week or more in fall camp may mean for the season
Sanchez: If I can't practice, I can't practice. It is as simple as that. It ain't about that at all. It's easy to sum it up if you're just talking about practice. We're sitting here, and I'm supposed to be the franchise player, and we're talking about practice. I mean listen, we're sitting here talking about practice, not a game, not a game, not a game, but we're talking about practice. Not the game that I go out there and die for and play every game last it's my last but we're talking about practice man. How silly is that?
On whether his absence will negatively affect the development of other offensive players
Sanchez: How in the hell can I make my teammates better by practicing?
