No it was not. If you look closely at the review, you see the end of the ball hit the ground, and the ball's knocked loose, completely out of his arm, and he falls on it. By the NFL's own rule, even if he had possession going down, he did not complete the requisite "football action" to make it possession and a catch (which, by the way, is a terminally stupid rule).
Problem is...it was very tough to see. Rather subtle, and partially blocked by his arm. It was conclusive IF you saw it...but it was easy to miss, particularly on a time limit (took me more than 90 seconds to see it). Guess the ref just missed it. C'est la guerre.
