Sounds like the nick/spine compression caused a double stinger. Iupati probably couldn't use his arms/shoulders to get up. Once that happened, medical personnel went into precaution/safety mode. Better to be safe than sorry.
I am glad he wasn't seriously hurt & should be able to play on Sunday.
Wow. I'm pretty shocked after seeing that injury. Figured at best he'd need a week or two.
Their list of injured is growing and looked concerning the other day (Floyd, Iupati, Redding, Brown, etc.). The good news is most were probable or questionable, just held out of practice.
