​The Baltimore Ravens had hope before kickoff last Sunday. Ahead of their kickoff on Thursday, most of that hope has vanished with two months left in the season. The Ravens suffered not only one but two quarterback injuries on Sunday. Lamar Jackson dislocated his right thumb on his first play back from an ankle injury, then Tyler Huntley injured his toe. Both players are on injured reserve. Before last Sunday, you would have had to have watched a lot of preseason football to know Joe Fagnano was the Ravens’ third-string quarterback. The undrafted rookie is now elevated to QB1 for their game on Thursday night against a very good Jacksonville Jaguars team. There is help on the way next week, as the Ravens reportedly were finalizing a deal for Cardinals quarterback Jacoby Brissett, but Fagnano will get at least one game. Fagnano started his college career as a walk-on at Maine. He went to UConn after that and had an impressive 28-to-1 touchdown-to-interception ratio for the Huskies. He still went undrafted and signed with the Ravens with no money guaranteed. In his first NFL action last week, he completed 10-of-21 passes for 91 yards. He will benefit from getting starter’s reps in practice, even though it’s a short week. It’s still a very tough assignment.

They’re up to No. 2 in DVOA behind the 49ers and are the only team that ranks in the top-five of offense, defense and special teams in DVOA. Three of their five wins have come by 24 or more points. It looks like they’ll run away with the AFC South. The Ravens are just trying to stay alive in case Jackson can make a return sometime late in the season. They have to wait one more week for Brissett to be the bridge quarterback to that. This week, they’re relying on an undrafted rookie to help pull off an improbable win. Who needs it more?It’s reasonable to say the Ravens. If they win they’ll be 5-4 with Jacoby Brissett coming on board. The season wouldn’t technically be over at that point. However, Baltimore’s chances of staying afloat over the second half of the season and also having Lamar Jackson return are slim. When you lose a two-time MVP quarterback to injured reserve, there’s not much you can do about it. The Jaguars are cruising along at 5-2 and look like a legitimate Super Bowl contender. They might not be the more desperate team, but they’re the one with a bright future this season. They need it more just because a loss to a reeling team with an undrafted rookie quarterback would ruin the idea that the Jaguars can win a championship. Key player: Ravens RB Derrick HenryIf the Ravens can pull off an upset, it will be because the defense plays great and the offense carries its quarterback. That formula puts a lot of pressure on Henry. It won’t be easy against a Jaguars team that will likely come in
