I'm looking again for the NFL's ruling on this but I just can't recall the guy's name that they ruled on. I'll keep looking.
For those saying it's clear, though, that it should have stood, here's the guy that's now NBC's ref consultant Jim Something
and his comment was "Going to the ground to complete the catch so by rule, he must control the pass throughout the process not just break the plane." so he thinks they blew the call as well.
