Dolphins vs. Ravens NFL betting preview It's been an unfortunate season for both franchises thus far, but both are coming off of wins against teams that were .500 or better last week. With Michael Penix Jr. out, the Dolphins hammered the Falcons 34-10 while the Ravens overcame Lamar Jackson being held out to beat the Bears 30-16 at home with Tyler Huntley starting. Tua Tagovailoa threw for four touchdowns to spur Miami's win while Tyler Huntley led scoring drives on six of eight possessions, including a pair of Derrick Henry touchdowns. With Lamar Jackson potentially returning in this game, the Ravens are favored by 7.5 while the over/under is 50.5 points. There are also dozens of NFL player props already available for play, including anytime touchdown scorer bets. Derrick Henry has the shortest odds of any player (-215) while De'Von Achane is priced at -150.
