3 things we know, 3 things we don't about the Ravens gameplan for Week 1 vs. Houston

We're less than 36 hours away from watching the Baltimore Ravens take the field of the M&T Bank Stadium for the first time this season.

The Flock will host the lowly Houston Texans on Sunday, and the outlook of the matchup is becoming a little bit clearer with each passing hour.

Between the latest press conferences, the release of a few injury reports, the analysis from across the NFL world, and our own coverage of the Ravens at Ebony Bird, we've put together a summary of what we know and what we don't know about Baltimore and Houston entering Week 1.

Here's everything you need to know ahead of Sunday's season opener.

1. We don't know: Who will be Lamar Jackson's backup?

It's very clear who will be out there in the pocket come Sunday's first offensive snaps for the Ravens. Who will be waiting on the wings, just in case Lamar goes down at some point, is still all the way up in the air.

Incumbent QB2 Tyler Huntley suffered a hamstring injury back in the first game of the preseason against the Eagles and he had not practiced with the team until earlier this week. However, he was never listed in the Ravens' injury report through the last five days.

Veteran Josh Johnson was cut by the Ravens before the franchise trimmed its roster to a 53-man size, but the Flock later re-signed him while releasing QB4 Anthony Brown.

Speaking to the media after Friday's practice, head coach John Harbaugh didn't give us any clue about who will be Lamar's backup in Week 1, or even if the team will carry the two reserves into their gameday squad to face Houston.

"We'll go week to week based on the circumstances right now of where we're at, what are needs are that particular week,” Harbaugh said per BaltimoreRavens.com. “We'll just figure it out as we go. We're just very blessed to have three really good quarterbacks and have two guys who are very capable of doing the job."

Asked about the chance of backing Lamar up, veteran Johnson said that "It's up to the coaches to decide who they want out there," acknowledging that "We all know who the starter is."

Johnson had a strong preseason and should be the actual QB2 because of that and his healthier situation. For now, though, we don't know if that'd be the case or not.
