No, Mshinu is right, the shards hit the mind control disc and which released Bill from it. Bill then stopped fighting and tried to talk. Which is when Hulk hit Bill with a cheap shot.
The injury he suffered should still be present during Fear Itself based on continuity, but it's not as severe and is manageable after Loki hid the seed or what have you.
I know this but Bill did hit a cheap shot in the beginning too. Mishnu stance was the fight was completely one-sided in Bill's favour up until this point which it wasn't. BRB started strong (which you would expect), then Hulk came back into it whilst Bill became more and more desperate. The fact is Bill had the advantage and he still lost, he used blasts, combinations of punches with hammer strikes and a hammer throw. He couldn't keep Hulk down whereas Hulks full powered punches nearly killed him.
The point is Hulk came out looking superior to Bill who is on average levels Thor's equal, in Marvels animation Hulk always has Thor's number.
In the comics it's not so one sided, past fights between these two generally ended in stalemates but it seems like Marvel have changed their stance on that and have established the Hulk as the superior of the two when they go head to head.
