What's the deal with Price's side line catch/non-catch?

[ghz in pittsburgh]

at the time but heard the commentators talked about it challenging it later. The game moved on and noone talked about it again.

Maybe Jauron was hesitant to challenge it because challenges haven't been working out as well as he'd like (or he just has no faith in officials after last week)
It was a catch..I think we would've won the challenge
