Underdog uses official league statistics provided by reputable partners and only includes statistics from sporting events the relevant league deems to be official.
We strive to quickly resolve contests and award prizes while ensuring accuracy. Final scores will be verified within 72 hours of the last game each week. Typically, once a contest is settled by Underdog, any subsequent scoring updates or statistical corrections from our partners will not affect the already-finalized contest results.
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.
