The Texans are halfway through the preseason and are in the stretch run to real football. The best news is they have remained relatively unscathed on the injury front. They suffered one significant one Saturday night when cornerback Kevin Johnson went out early with a concussion.

This was going to be a key year for Johnson. He played all 16 games as a rookie, but just six in his second year and 12 last year in a season that was a complete disaster. As a first-round pick with multiple injuries and performance issues, Johnson is very close to getting the dreaded “bust” label.

It is his second concussion, and came on a play where he was badly beaten. Johnson appears to be OK, but concussions are dicey, and there is no way of knowing when he will return. Johnson has shown flashes at times, but coming off a rough season and multiple injuries, it is safe to say the Texans can’t count on him. Considering it is one of the thinnest positions on the roster, it is an unfortunate turn of events.

It means Aaron Colvin likely starts alongside Jonathan Joseph, but now Johnson Bademosi moves up a spot. Bademosi is a terrific special teams player but a below average corner. There does not appear to be another answer on the roster unless Kareem Jackson moves back from safety, but that would weaken what appears to be a strength. 

The Texans are having former Ram Kayvon Webster in for a visit. He played in 11 games last season and is also coming off an injury. He is nothing special, but likely better than any options on the roster.

Veteran Dominique Rogers-Cromartie remains available as well.

Other than Johnson, none of the key injured players from last year have seen much time. In reality, they should not. Deshaun Watson has played two series, and there is no reason to put him back out there. Same goes for J.J. Watt and Whitney Mercilus.

Watson looked sharp in his work against the 49ers, but starting quarterbacks are supposed to do that in preseason games. The good news is he is moving well and looks ready for the regular season.

The key over the next two games will be to keep the important players healthy, and see who earns the bottom roster spots.

What have we learned so far?

Pretty much what we already knew. The biggest question marks coming in were offensive line, running back depth behind Lamar Miller and depth on the corners. With Johnson’s injury, the latter becomes an even bigger issue.

The OL has looked OK in the first two games, but we really won’t learn much about this group until the real games start.

After Miller, the Texans don’t appear to have anything above mediocre players at running back. This group could look a lot different if D’Onta Foreman is able to return, but he is coming off an Achilles injury and should not be counted on.

Still, Watson appears to be healthy, and J.J. Watt has looked good in camp, even if he hasn’t played a game, so there are positives. But until they play for real, most of the big questions will remain unanswered. 

Meanwhile, Brandon Weeden has looked pretty solid as Watson's backup. Obviously if Watson is down for any extended time, the Texans are in trouble, but if you had to play Weeden 2-3 games, you would feel much better than you did last season. The interior defensive line and linebackers also appear to be much deeper this season.

The Johnson injury is the one added concern, and hopefully it can be remedied by adding another player. Or maybe he recovers quicker than expected. But if that is your biggest problem when the season starts, you can live with it. 

In fact, you probably should have expected it.
