I am in the extreme minority here but this does not bother me one bit.
The guy was seriously injured and played through it.
He knew he wasn't close to right and needed 48 hours to gather himself mentally before undergoing an MRI which might have ended his season again.
I don't think he plays this week and I don't think his 48 hour hiatus matters one bit in whether or not he does since he is too sore to practice.
But I also don't think you need to treat NFL players like they are part of an infantry unit.
Dez is a high-priced insanely rarely talented worker and you handle those guys differently.
