Underdog Fantasy promo code COVERS delivers $100 bonus for Rams vs Cardinals

The Underdog Fantasy promo code unlocks a generous welcome bonus that turns a modest $5 entry into $100 in bonus credits. New users must enter the code COVERS during registration to qualify for this offer, which applies to both draft contests and pick'em games featuring Sunday's Rams-Cardinals clash.

The bonus structure works straightforwardly: make your initial $5 entry on any available contest, and Underdog Fantasy credits your account with $100 in bonus funds within 72 hours. For example, suppose you enter a pick'em contest predicting whether Stafford will throw over 1.5 touchdown passes against Arizona's defense. In that case, your $5 entry qualifies you for the full bonus regardless of whether your picks win or lose.

Key terms include a 1x wagering requirement that must be completed within 14 days of receiving the bonus. The bonus expires 60 days after it is unused, and account verification is required before any winnings can be withdrawn. This promotion is not available in Maryland, Michigan, Pennsylvania, and Ohio.
