Did I miss something

The article says that Henderson was moved back to the PS.

But as he was signed to PS originally anyway and elevated to the active roster for the Pittsburgh game, this isn't really news.

My understanding was that Freeman was signed to the active roster as he couldn't be elevated from the PS anymore.
Henderson was signed to PS and Gaskins was sign to active roster and has to be kept for 4 games as he was signed off a PS.
