Colts vs 49ers Monday Night Football DFS preview

The Colts (8-6) are on a downward spiral after losing Daniel Jones for the year. But before that, the organization went all-in with him at the helm by mortgaging a handful of future first-rounders for Sauce Gardner, who is also hurt.

The 49ers are trending in the right direction and getting healthier. Brocky Purdy is back, and Kyle Shanahan’s team is aiming to make another strong January run. NFL betting odds for this game have the 49ers at 5.5-point favorites on the road at Lucas Oil Stadium.

Check out our full betting breakdown for Colts vs 49ers.

Monday NBA DFS Preview

Tonight brings seven NBA contests to the board. The Oklahoma City Thunder, sitting at 25-3, square off against the Memphis Grizzlies at home in a standout matchup. OKC suffered a setback to Minnesota, 112-107, this past Friday, which snapped an extraordinary early-season run.

The squad has dropped two of its last three after that remarkable 25-1 tear. Ja Morant remains sidelined with an ankle issue for Memphis, while Shai Gilgeous-Alexander continues his elite scoring campaign at 32.5 points nightly (second in the league).

The Golden State Warriors (17-9) take on the Orlando Magic (20-6) at 10 p.m. ET at home. Stephen Curry has been a constant threat inside Chase Center this season, and the Magic bring a stout defensive unit that will test Golden State’s offensive rhythm.

It’s a great slate for some NBA picks and DFS. Underdog’s Pick’em format gives you options you simply won’t find on other platforms when tackling tonight’s full slate.

Monday NHL DFS Preview

We’ve got four NHL games on the ice, headlined by the Philadelphia Flyers (17-10-7) hosting the Vancouver Canucks at 7:30 p.m. ET. The Flyers have been absolute grinders at the Wells Fargo Center (10-5-4 home record) and are sitting as -135 favorites. Vancouver has been decent on the road but struggles to score consistently (2.8 goals/game), making Philly the sharp side to control the tempo tonight.

Out West, keep your eyes on the Anaheim Ducks (21-13-2) hosting the reeling Seattle Kraken at 10 p.m. ET. If you haven’t been paying attention, the Ducks are fighting for the top spot in the Pacific, led by Leo Carlsson (41 points, 17 goals). Seattle is in freefall, having lost 10 of their last 12 games. Anaheim has won six of its last seven home games against division rivals—don’t overthink this one.

Rounding out the slate, the Tampa Bay Lightning are heavy home favorites against the St. Louis Blues at 7 p.m. ET, while the Los Angeles Kings look to feast on the Columbus Blue Jackets at 10 p.m. ET. The Kings (-185) need these points to stay in the playoff hunt, and a home date with Columbus is about as soft a matchup as you’ll find on a Monday night.

Tonight’s NHL matchups are a great spot for your Underdog Promo Code! Don’t miss out on the fun, and jump into Underdog Fantasy today!
