I thought it was a fumble, but that's just my personal opinion. The call from the referee was his knee was down. So I guess that was the right call. They got instant replay and looked at it a few times, so evidently they saw something that I didn't see or they knew a rule that I don't know. I thought it was a fumble, but again, that's just my personal opinion.
