Live player stats are coming soon. Today a player prop (passing, rushing or receiving yards, receptions, anytime TD) shows Updates after the game while the game is on, and it's graded from the final box score overnight.
When live player stats arrive, a prop that clears its line before the final will show Unofficial until final, because stats can be corrected until the game ends.
Live games show Live score · game clock unavailable: the score is live, but the quarter and clock aren't, so we never show halftime or clock wording.
