This is the play where KG got hurt. First of all… you can see he took a knee to the calf (:06 in) when he jumped into David Lee. That's some charley horse action right there. If this is what it looks to be… it's just a bruise and KG will probably wear some sort of wrap or legging to keep it warm and loose over the next couple of games.
Secondly… nice play. I know he's done it forever… but it's still amazing to see a 7 footer doing that.
