Bears quarterback Caleb Williams saw progress in the passing game from Week 1 to 2.

After completing 14 of 29 passes (48.3%) for 93 yards in a season-opening win over the Titans, the highly touted rookie connected on 23 of 37 passes (62.2%) for 174 yards with two interceptions in last Sunday night's loss in Houston.

"I would say the pass game, rhythm and things like that, felt good," Williams said Wednesday. "Obviously, I had two stupid mistakes that won't happen again. But I think I got better getting the ball out of my hands, it felt like, trying to stay in the right range of timing for the offensive linemen and myself and the routes and things like that."

That timing was disrupted by frequent Texans blitzes.

"A lot of times when it's a five-man [rush], which we got some last week, it's more about just games, twists and pick games going on inside there," said coach Matt Eberflus. "We've got to work on passing those off. That's what they did last week."

When they returned to the practice field Wednesday, the Bears focused on correcting the pass protection mistakes they made against the Texans.

"It's not scheme," Eberflus said. "It's not this or that. It all comes down to basics and fundamentals and we've got to keep working on that as we go."

Asked if he was contemplating any changes to the starting offensive line, Eberflus said: "We're looking for continuity and consistency and communication and getting better. That's what we're focused on. I go back to my original comment: it's fundamentals and basics. It's important that we get that down as a group. So we're going back to that. That's what wins football games."

Given the success that the Titans and Texans had blitzing Williams, the Bears are expecting future opponents to employ the same strategy.

"We've just got to be on it," said receiver DJ Moore. "Know our calls, know our protection, know when we're 'hot' just to help Caleb out. I know we've got to nip that in the [bud] because it's a copycat league and other teams are going to try to bring the house at him."

In practice, the Bears will also concentrate on improving a rushing attack that ranks 28th in the NFL. On Sunday, they'll face a Colts defense that is last in the league against the run, having permitted 474 yards in losses to the Texans and Packers.

"I think one of the things we'll be able to do really well soon is be able to run the ball," Williams said. "I'm trying to figure out which runs exactly fit well with our personnel, the people we have. I think that's a thing that's going to emerge here really soon."

After only two games, the Bears are still working to forge their offensive identity.

"We're figuring out what we do well," Eberflus said. "I believe that we got better last week in terms of rhythm, timing, passing, distributing the ball to the skill. Now we're working run game, all the other things that come off that.

"We're a work in progress. I believe in the coaches and I believe in the players, and the guys are working to get that done."

Injury update

Receiver Keenan Allen (heel), left guard Teven Jenkins (thigh), fullback Khari Blasingame (hand/knee) and defensive tackle Zacch Pickens (groin) did not practice Wednesday.

Eberflus said that Allen, who sat out last Sunday night's game in Houston, is "still working through his heel situation" and "we're trying to get him back on the grass as fast as possible."

Eberflus revealed that Jenkins sustained a deep thigh bruise versus the Texans and was skipping practice "to get strength back into that and to get that thing healed up."

Eberflus is confident that Jenkins will play Sunday in Indianapolis.

"We do feel good about it," said the Bears coach. "We'll see where it goes for tomorrow. It's a power thing and then him feeling comfortable and the trainers feeling comfortable for him to come back in."

Players limited in practice Wednesday were receiver Rome Odunze (knee), offensive linemen Nate Davis (groin) and Kiran Amegadjie (quad), and defensive linemen Montez Sweat (elbow) and DeMarcus Walker (foot).
