Underdog uses official league statistics provided by reputable partners and only includes statistics from sporting events the relevant league deems to be official.

We endeavor to promptly settle contests and distribute prizes, but it is also important to us to make sure we do so accurately. On a weekly basis, final scores will be confirmed within 72 hours after the final game for that week is played. Normally, any scoring changes or stat corrections provided by our partners after a contest has ended and Underdog has settled the contest will not impact the already-settled contest.

However, Underdog reserves the right in its sole discretion to revise scores after they are released in the unlikely event of potential scoring error by a provider or Underdog. In those circumstances, the contest results may be altered, and payments may be distributed or reversed based on the correction.
