Underdog Promo Code DIMERS: deposit match up to $1,000 for Commanders vs. 49ers on Monday Night Football — Underdog promo code DIMERS: first-deposit match up to $1,000, Play $5 Get $100, five free Rips packs. Terms apply.

The Underdog promo code DIMERS unlocks a first-deposit match of up to $1,000 in bonus funds for Commanders vs. 49ers on Monday Night Football, alongside a Play $5, Get $100 bonus and five free Rips packs. The 5-0 49ers host the 1-3-1 Commanders at Levi’s Stadium at 8:15 p.m. ET on ESPN/ABC, and with Christian McCaffrey at 65.8% on Dimers’ model to score a touchdown, the Monday night player board is where the matched funds go to work.

What is the Underdog promo code for Monday Night Football

The Underdog promo code is DIMERS. Entered in the promo code field at registration, it triggers three things for a new Underdog user: a match on the first deposit of up to $1,000 in bonus funds, a $100 bonus after a $5 qualifying play, and five free Rips packs worth up to $750 combined. The deposit match is the largest single figure of any code on Dimers’ NFL Week 6 board, and the $5 play requirement is the smallest.

Underdog’s menu leans toward player markets, so the matched funds and the $100 bonus suit a user who wants to take positions on McCaffrey, Mike Evans, George Kittle, Jayden Daniels and the rest of the two offenses rather than on the 49ers’ 78% moneyline.

How to Claim the Underdog Promo Code DIMERS Bonus

Open Underdog through this link and start a new account.
Enter the Underdog promo code DIMERS in the promo code field during registration.
Verify your identity and location.
Make your first deposit — Underdog matches it with bonus funds, up to $1,000.
Place a $5 play on a Commanders vs. 49ers market to trigger the $100 bonus, then open your five free Rips packs.

Tip: the match applies to the first deposit only, so the size of that deposit sets the size of the bonus. A $5 play on McCaffrey to score a touchdown is enough to trigger the $100, and the matched funds can then be spread across the rest of the Monday night board.

Why Commanders vs. 49ers Is the Game for Underdog Promo Code DIMERS

A one-game night is the simplest place to start an Underdog account: one roster of players on each side, one kickoff, and a full week before the Sunday slate to use whatever is left of the matched funds. The 49ers rank third in points scored and fourth in points allowed and beat Seattle 32-29 on four takeaways, with Evans catching seven passes for 113 yards and a touchdown. The Commanders rank 21st and 29th and tied the Giants 27-27 in overtime, with Daniels running for two scores in his return from an elbow injury.

Dimers’ model projects a 30-21 San Francisco win, which means roughly six touchdowns’ worth of scoring to distribute across the two offenses — and a touchdown-scorer board where the 49ers’ three leading candidates are all above 43%.

Commanders vs. 49ers Touchdown Scorers: Dimers’ Model for Underdog Promo Code DIMERS

Dimers’ Commanders vs. 49ers prediction page publishes the model’s anytime-touchdown and first-touchdown probabilities for each team’s leading candidates.

Player	Team	Dimers anytime TD probability	Dimers first TD probability
Christian McCaffrey	49ers	65.8%	16.6%
Mike Evans	49ers	48.8%	10.4%
George Kittle	49ers	43.6%	8.9%
Rachaad White	Commanders	38.8%	7.3%
Stefon Diggs	Commanders	30.3%	5.4%
Terry McLaurin	Commanders	29.3%	5.2%

McCaffrey at 65.8% is the only player on either side the model has as more likely than not to score. Evans and Kittle are near coin flips for San Francisco; White leads Washington at 38.8%, with Diggs and McLaurin around 30% after a week in which Diggs had his first limited practice since Week 4 and McLaurin was on a reduced workload. Underdog’s own player lines for Monday night are on the app.

Commanders vs. 49ers Odds and Dimers’ Prediction

For the game itself, Dimers’ model has the 49ers at 75.9% to win and the Commanders at 24.1%, with a projected score of 30-21. The model gives San Francisco a 53.2% chance of covering the 7.5-point spread and the Under on 52.5 total points a 54.5% chance, the larger of the two leans. The prediction markets price the 49ers around 78% to win, the spread at 50% either way and the Over 52.5 at 48%, so the model is slightly lower on the favorite, slightly higher on the cover and slightly lower on the scoring than the market.
