Nah. It was probably a symptom or set of symptoms that could have indicated some lingering infection which can happen.
They don't all go ham the moment they're left unattended, especially among the freakish athletes that comprise pro sports teams... except Baseball... no sport that has had solid players like John Kruk and Greg Luzinski can claim to be fully comprised of athletes whereas in football, soccer and hockey, even kickers and goalies have to display sufficient athleticism (no kicking Sheldon Coopers, for example).
Anyway, I digress.
I've had these issues at the Dr before where the symptoms COULD be a number of things, but they always check the most serious thing first...which is both prudent and can be unnerving.
Worst case scenario was that he had a lingering infection which might have required further surgery or an invasive round of antibiotic intervention (which woulda screwed his digestion all to hell, liking causing weight loss as a result of the antibiotics killing the good gut fauna) or both.
So yeah, w/e they're doing, the fact that it's not a lingering infection is 100% great news.
I expect him to be back, get some rookie reps and then be able to step up next season... which was always gonna be the case with Floyd and Ebukam in front of him and since it's unlikely either will be here next year, I'm sure he'll get his turn as well as Jachai Polite and the rest of the OLB depth chart.
