ByUpdated: Aug 17, 2025 4:05PM UTC . 4 min read

Week 2 of the NFL preseason continues Sunday, Aug. 17, with two games featuring Jacksonville Jaguars visiting the New Orleans Saints in the early afternoon before the Buffalo Bills face the Chicago Bears in the evening. There's also a loaded 15-game MLB slate, five contests in the WNBA and a Premier League match between Arsenal and Manchester United on Sunday's schedule.

Bettors interested in NFL betting, MLB betting, WNBA betting and soccer betting can take advantage of the latest BetMGM bonus code SPORTSLINE to receive up to $1,500 in bonus bets.

How to claim the BetMGM promo

The latest BetMGM offer is available for new users of legal age in a state where BetMGM legitimately operates. Here's how to sign up.

  1. Click "CLAIM BONUS" on this page. You will be redirected to BetMGM.
  2. Fill out all the required information to create an account. Be sure to use the code SPORTSLINE when signing up.
  3. Make a minimum deposit of $10.
  4. Place a wager on any market. There is no minimum odds requirement.

You will receive bonus bets if your first bet loses, up to $1,500. If you wagered less than $50, you'll receive one bonus bet slip equal to the wager amount. If you wagered $50 or more, you'll receive five bonus bet slips of equal value totaling the wager amount. For example, if you wagered $100 under the promotion and lost, you'll get five $20 bonus bet slips. Bonus bets cannot be cashed out or withdrawn. They expire in seven days. If you win a wager using bonus funds, you'll get the winnings but not the stake.

Take a look at the best sportsbook promos available, including the one from BetMGM.

Best bets for Sunday, August 17

The Bears are going to be playing their starters for at least a series, which means Caleb Williams gets to showcase his skills in Ben Johnson's offense against Buffalo. Chicago's quarterback has dealt with more scrutiny this offseason but can put a lot of that to bed in front of the home crowd Sunday evening. The Bills are unlikely to roll out their top players, although head coach Sean McDermott has not ruled out Josh Allen playing a series or two. Chicago is a 2.5-point favorite at BetMGM in this contest.

The San Francisco Giants have lost seven games in a row and will attempt to avoid another sweep when they face the Tampa Bay Rays Sunday afternoon. San Francisco is sending Logan Webb (10-9, 3.34 ERA) to the bump in this series finale while the Rays counter with Ryan Pepiot (8-9, 3.86 ERA). Tampa Bay has won three games in a row and the SportsLine Projection Model rates Rays +1.5 as an "A" grade play. The visitors cover in 71% of simulations.

Five WNBA contests are spread out across Sunday's schedule with the Atlanta Dream taking on the Golden State Valkyries in the evening to close out the slate. The Dream have quietly climbed to the top of the Eastern Conference, sitting a half-game ahead of the defending champions Liberty. The Valkyries remain a force at home with a 10-5 record in the Bay Area, and have won four in a row. WNBA expert Max Meyer has locked in several player props for Dream vs. Valkyries among his best bets for Sunday's games.
