Gee, you must have been watching the same game I was watching. Yes, Seahawks QB was not knocked down by contact, he slipped and was touched WHILE HE WAS UP, NOT AFTER HE WAS DOWN! That was a fumble recovery that was denied the Steelers by the officials.
On the fumbled pass by the Seahawks receiver that was ruled not a fumble, IT WAS A FUMBLE! The Steelers would have recovered if the OFFICIALS hadn't blown the whistle to stop the play.
But all the whiners say all the officiating went against the poor, unfortunate Seahawks, who would have won the game without the bad calls. Huh?

Yep, that was a real bad call.
