The women play early tomorrow morning, USA time. I'm almost 100% sure the gold medal game is online live at 6:20 AM EST (3:20 PST, ugh!) and then a replay of at least some of the game will be on between 10-1 PM on NBC
The men play Serbia in the semi on Friday 7:40 AM EST, which will be online live, but I don't know when it'll be on TV. My guess is that might be determined on if we win or lose.
Wish the women luck! I know they're gunning for the gold, and especially happy that the player they thought broke her hand against Australia has been cleared to play!
