no dude. the replay was clear. he had possesion when his knee was down.
Anyway...int he last two minutes of a half or game...FORWARD fumbles cannot be advanced.
correct me if I am wrong though...
But I am positive that his knee was down and he had possesion. the replay officials also agreed. They could have called that fumble and recovery as well...although i think the rule is you cannot advance a fumble in the last 2 minutes.
