The Chicago Bears were back at Halas Hall for their fourth practice of training camp on Friday. Despite a weather delay that forced it to be a closed practice, the Bears were able to get some work done in the rain.While the offense got off to an impressive start to training camp, it was the defense's turn to shine on Saturday, aided a little by the weather conditions. Quarterback Caleb Williams and the offense struggled to get into a rhythm, and the secondary was finally able to best what's been a dominant passing game. There were also some updates in position battles at left tackle and nickel cornerback in the final practice of this first week before the pads come on Monday.Let's recap Day 4 of Bears training camp:TakeawaysDefense finally wins the day: For the first three practices, it was the offense that dominated training camp. In fact, the passing game looked unstoppable. But the defense has finally closed the gap, and they had their best practice of the summer. According toAdam Hoge, it was a "bounce back day" for the defense, where safety Coby Bryant and the secondary shined. Bryant had "a really nice interception over the top on a Caleb Williams deep ball" and he "tracked it well."Herb Howardcalled it a "completely different day at practice" compared to the first three days, and he praised Bryant and cornerback Jaylon Johnson as the standouts. Bryant had the one pick of Williams, but Howard said he nearly had two more. Howard said the defense was "flying around all morning."Rough outing for Caleb William and passing game: After a dominant first three practices at training camp, quarterback Caleb Williams and the offense had their worst showing of the summer in the rain. According toHerb Howard, "Caleb was not sharp today with his accuracy nor timing. He and Luther Burden, dominant to this point in camp, could not sync up. It was a combination of timing, inaccuracy, and a drop." In the end-of-half two-minute drill, Williams threw three straight incompletions to Burden, perBear Report. Jeff Buckhalter added that Williams had a "few rough reps/attempts/near picks" during practice. The conditions certainly impacted the passing game, asAdam Hogenoted that there were "too many drops in the slick conditions too. Most of practice was in a light rain." According toZack Pearson, "felt like the first team offense couldnt get into a rhythm. Drops. Slipping."Left tackle rotation continued with Jedrick Wills Jr.: TheBearscontinued their rotation in their left tackle competition. On Days 1 and 2, it was Braxton Jones working with the starters. On Day 3, it was primarily Kiran Amegadjie. On Saturday, Jedrick Wills Jr. got his turn to work with the first-team offense, and Jones ran with the second team, perAdam Jahns. While Jones is the favorite to win the starting job, Chicago will continue to give everyone an opportunity to compete for the role, so expect the rotation to continue when the Bears return to the practice field on Monday, which will be the first padded workout of the summer.Jaylon Jones at nickel with the starters: Kyler Gordon remains sidelined with a calf injury on the physically unable to perform list, which has opened the door for competition at nickel cornerback. Jaylon Jones has primarily worked in the slot with the first-team defense while Cam Lewis has also gotten his opportunities Josh Blackwell and rookie Malik Muhammad have also gotten looks. But on Saturday, it was Jones working with the starting defense, according toJosh Buckhalter.Rookies Zavion Thomas, Jordan van den Berg flash: The Bears are hoping they receive some big contributions from their rookie class, and both wide receiver Zavion Thomas and defensive tackle Jordan van den Berg had a standout day. Thomas developed a nice rapport with backup quarterback Tyson Bagent, and the pair connected for a touchdown during a two-minute drill to end practice. According toMark Carman, Thomas got a "ton of balls" thrown his way on Saturday. Carman added that van den Berg "flashed" during a non-padded 1-on-1 session against rookie center Logan Jones. -- Alyssa BarbieriStudsS Coby Bryant: Coby Bryant stood out as arguably the best performer from Saturday's practice according to those in attendance. Bryant picked off quarterback Caleb Williams on a pass intended for wide receiver Maurice Alexander. He read the pass well and took advantage of an overthrow to bring in the pick.Bear Report's Zack Pearson notedthat Bryant could have had another interception later on.CB Jaylon Johnson: The defense as a whole won the day with Bryant leading the way with his interception, but Jaylon Johnson also stood out for his play as well.CHGO's Mark Carmansaw Johnson make a deflection on a pass that nearly led to an interception by Jack Sanborn.Mason Williams of theTimes of Northwest Indiananotesthe Bears had seven pass breakups during the practice.WR Zavion Thomas: It wasn't all bad for the offense on Saturday. Despite the defensive dominance for much of the day, the Bears offense was still able to find the end zone. Rookie receiver Zavion Thomas flashed with a touchdown to end practice. Quarterback Tyson Bagent found Thomas on a quick out route where the rookie reached the ball across the pylon for the score with Josh Blackwell in coverage. -- Brendan SugrueInjury updatesThe only notable absence from Saturday's practice was running back Kyle Monangai, who was not spotted on the field for the third straight day. It's worth noting that linebacker Jack Sanborn did exit practice early, but the reason is unknown. The players previously announced on the non-football injury and physically unable to perform lists were sidelined: linebacker T.J. Edwards, cornerback Kyler Gordon, offensive tackle Ozzy Trapilo, safety Elijah Hicks, linebackers Keyshaun Elliott and Noah Sewell and defensive end Shemar Turner.HighlightsOh, hi @dae2walker pic.twitter.com/KAvdTZC3F9 Chicago Bears (@ChicagoBears) August 1, 2026.@_CobyBryant_'s been ballin' pic.twitter.com/9nWNcIN7h1 Chicago Bears (@ChicagoBears) August 1, 2026ZT with the TD pic.twitter.com/nDR3mEW9N4 Chicago Bears (@ChicagoBears) August 1, 2026Press conferences (Richard Hightower, Jaylon Johnson, Cole Kmet, Zavion Thomas)What's nextThe Bears have an off day on Sunday after their first four practices of the summer.
