The Buffalo Bills are expected to pick up their first loss of the season against the always tough Baltimore Ravens Sunday night at M&T Bank Stadium.

Only one site predicts Josh Allen, James Cook and the rest of the Bills will come out on top the Ravens, led by Lamar Jackson and the Derrick Henry, according to our roundup of NFL Week 4 predictions.

The Ravens are a 2.5-point favorite over the Bills, according to BetMGM. The money line is Ravens -140 (bet $140 to win $100) and Bills +115 (bet $100 to win $115). The over-under is 46.5.

This is who the experts think will win this week:

Democrat and Chronicle: Ravens 23, Bills 17

Sal Maiorana writes: "With the Steelers off to a 3-0 start, the Ravens are already two games behind in the AFC North and as one of the highly-rated Super Bowl contenders going into the season, they can’t continue to keep stumbling. They’re coming off a nice win in Dallas, and they’re at home so they’ll take care of business."

The Arizona Republic: Ravens 24, Bills 20

Jeremy Cluff writes: "If the Ravens can get to 2-2 after the 0-2 start, it will be a great sign for the rest of their season. We think the defense will be key in beating the Bills."

The Sporting News: Ravens 23, Bills 20

Vinnie Iyer writes: "The Bills have been having fun running the ball to support Josh Allen in their diverse and balanced offense. The Ravens can be relentless running at a high level with Lamar Jackson and Derrick Henry, and that's how to attack Buffalo's defense. Allen will run into some turnover trouble against Baltimore's back-end looks after the Ravens apply some good inside pressure on him."

Sports Illustrated: Ravens

Iain MacMillan writes: "It's time to sell high on the Bills. They have got off to an unbelievably strong start to the season, but I believe we're going to see some regression from this team in the coming weeks. A road game against the Ravens could be the time for exactly that to happen. Despite being 1-2, the Ravens rank fifth in the league in Net Yards per Play and their offense is averaging a blistering 6.6 yards per play, the best mark in the NFL. More important than the Ravens' offense is their defense, specifically their ability to stop the run. The Ravens have allowed just 2.8 yards per carry, the fewest in the NFL by 0.7 yards per rush. That's going to be a tough challenge for a Bills team that has embraced the run this season, running at a top five rate amongst all teams. I'll take the Ravens in this must-watch Sunday Night Football showdown."

CBS Sports: Ravens 23, Bills 20

John Breech writes: "It took three weeks, but the Ravens have finally figured out how to win games: They just need to run the ball. ... With Derrick Henry, the Ravens offense is basically a freight train that's rolling down the tracks at full speed, and not many teams have a strong enough defense to slow down a freight train. The Bills have struggled to stop the run this year, surrendering an average of 118.3 yards per game and that number is likely only going to get worse after this showdown on Sunday night. The Bills are coming off a short week after playing on Monday night in Week 3, which is definitely an advantage for the Ravens.
