Early Payout Specials And Boost Builders For NBA: Celtics-Pistons

Underdog’s latest promo code THEGAMEBET which nets you $75 in bonus or entries for just signing up for an account and playing $5 is the only boost you need for the Celtics-Pistons matchup. The Pistons won their previous matchup 112-105 thanks to a double-double performance by All-Star guard Cade Cunningham who recorded 32 points and 10 assists. The 24-year old Cunningham, however, is listed as day-to-day heading into this matchup due to right wrist sprain which means other guys Jaden Ivey, Ausar Thompson, and Isaiah Stewart to step up here.

The Celtics, for their part, are hoping to bounce back from their previous defeat to the Pistons where they struggled badly from beyond the arc, just converting 10 of their 39 attempts. Versatile forward Jaylen Brown is expected to lead the Celtics offense here though one name that should step up here is sharpshooting guard Payton Pritchard who was only limited to 12 points last time versus the Pistons. Either way, you have to use our Underdog promo code THEGAMEBET right now and play at least $5 to grab an extra $75 for the Celtics-Pistons showdown. Here are a few plays that might be worth checking out if you don’t know where to start.

  • Jaylen Brown over 29.5 points
  • Isaiah Stewart over 1.5 blocks
  • Payton Pritchard over 2.5 three-point shots made
  • Jaden Ivey over 9.5 points
  • Ausar Thompson over 1.5 steals
