Well, he already went out to California and got a head start with Brady, so he basically already had his OTAs and stuff. Its going to suck that hes going to miss camp, but his spot on the roster is secure anyways and now it just gives other guys an opportunity in the preseason.
Hernandez is going into his 3rd year, so hes practically a veteran at this point and hes been spending that extra time with Brady. I'm not too worried, I'd rather have stuff like this at the beginning of the year than towards the end.
