The Indianapolis Colts traded veteran defensive tackle DeForest Buckner to the San Francisco 49ers on Tuesday, October 27, 2026, in exchange for a fourth-round pick in the 2027 NFL Draft. The move sends the three-time Pro Bowl selection back to the franchise where he began his professional football career.
The trade is part of a significant roster overhaul in Indianapolis following a disappointing start to the NFL season. The Colts also traded All-Pro offensive guard Quenton Nelson to the Seattle Seahawks earlier Tuesday, acquiring additional draft picks as the organization prepares for its future.
Buckner, 32, returns to a San Francisco team leading the NFC West with a 6-1 record. His arrival gives the 49ers an experienced interior defensive lineman as they address injuries and strengthen their roster for a potential playoff run.
The Colts confirmed the transaction Tuesday evening. Reports from the Associated Press and NBC Sports indicated that the deal was subject to Buckner passing a physical.
Buckner Returns to the Team That Drafted Him
San Francisco originally selected Buckner with the seventh overall pick in the 2016 NFL Draft out of the University of Oregon. He quickly established himself as a dependable starter and became an important part of the 49ers defense.
During his first four seasons in San Francisco, Buckner developed into one of the league's most productive interior pass rushers. He recorded 12 sacks in 2018 and added 7.5 in 2019.
Buckner helped the 49ers reach Super Bowl LIV following the 2019 season. San Francisco ultimately lost to the Kansas City Chiefs, and Buckner was traded to Indianapolis several weeks later.
The 2020 transaction sent Buckner to the Colts in exchange for a first-round draft selection. Indianapolis subsequently signed him to a lucrative contract, making him a centerpiece of its defensive line.
His latest move reverses that earlier trade, although the compensation is considerably different. San Francisco initially received a first-round pick for Buckner but is now reacquiring him for a fourth-round selection.
The veteran's familiarity with the organization could help his transition. Head coach Kyle Shanahan and general manager John Lynch were both in their current positions during Buckner's first stint with San Francisco.
Buckner Remains Productive at Age 32
Buckner has continued to produce despite entering his 11th NFL season. Through seven games in 2026, he recorded 31 combined tackles, four sacks and three passes defended.
His four sacks represent a significant contribution from an interior defensive lineman. Players at his position frequently face double-team blocking schemes and are responsible for disrupting both passing and rushing plays.
Across 158 career games with San Francisco and Indianapolis, Buckner has accumulated 683 tackles, 75.5 sacks, 101 tackles for loss and 196 quarterback hits. His career totals also include nine forced fumbles and 11 fumble recoveries.
Buckner earned first-team Associated Press All-Pro recognition in 2020 and was selected to the Pro Bowl in 2018, 2021 and 2023.
During seven seasons with Indianapolis, he recorded 47 sacks and 122 quarterback hits in 95 games. He started 90 of those contests, demonstrating his importance to the Colts' defensive front.
His recent production also follows a serious injury. Buckner underwent season-ending neck surgery in December 2025 but returned for the beginning of the 2026 campaign.
49ers Strengthen Injury-Depleted Defensive Line
San Francisco enters its bye week with one of the NFL's strongest records, but injuries have created challenges along its defensive front.
Defensive tackles C.J. West and Alfred Collins have dealt with injuries, reducing the team's available depth. Buckner provides an immediate veteran option who can line up alongside Osa Odighizuwa and rookie Gracen Halton.
Star defensive end Nick Bosa has also been sidelined with a calf injury. General manager John Lynch said Tuesday that the team expects Bosa to return following its Week 8 bye.
Having Buckner and Bosa available together could improve San Francisco's ability to pressure opposing quarterbacks. Buckner's presence in the middle of the defensive line may create opportunities for other defenders by forcing offenses to devote additional blockers to him.
The 49ers have recorded 15 sacks through seven games, placing them in the lower half of the league in that category. Adding a proven interior pass rusher gives the coaching staff another option for generating pressure without relying heavily on blitzes.
Buckner's return has already generated enthusiasm among his former teammates.
Tight end George Kittle celebrated the news on social media, sharing an old photograph featuring Buckner and fullback Kyle Juszczyk. Kittle wrote:
DEFOOOOO THE BOYS ARE BACK.
Kittle and Buckner played together in San Francisco from 2017 through 2019. Their reunion brings back a familiar connection from the team that reached the Super Bowl following the 2019 season.
Colts Make Major Changes After 2-5 Start
Indianapolis has taken a different approach as its disappointing season continues. The Colts are 2-5 and have lost three consecutive games, including their latest defeat against the Minnesota Vikings.
The organization fired general manager Chris Ballard last week, signaling a major change in its football operations.
The team's ownership is now led by Carlie Irsay-Gordon, who became principal owner and CEO following the death of her father, Jim Irsay, in May 2025. Her sisters, Casey Foyt and Kalen Jackson, also hold ownership and leadership roles.
Tuesday's trades suggest the Colts are prioritizing future draft resources over retaining established veterans.
Indianapolis sent Nelson to Seattle in exchange for a third-round selection in 2027 and a fifth-round pick in 2028. The Buckner transaction added another fourth-round selection in 2027.
Together, the two deals provide Indianapolis with three additional future draft picks while removing two prominent players from its roster.
Buckner's departure also creates a significant opening on the defensive line. He had been one of the organization's most reliable defenders and a respected veteran presence during his years in Indianapolis.
The Colts could continue evaluating their roster ahead of the November 10 NFL trade deadline. However, there is no confirmed agreement involving running back Jonathan Taylor or wide receiver Josh Downs, despite speculation about additional moves.
What Comes Next for Buckner and the 49ers
Buckner is entering the final year of his current contract and is scheduled to become an unrestricted free agent after the 2026 season. San Francisco has not announced a contract extension.
That means the 49ers are acquiring a productive veteran without a publicly confirmed commitment beyond the current season. His performance over the remaining games could influence whether the organization pursues a longer-term agreement.
San Francisco is off during Week 8 and is scheduled to return against the Las Vegas Raiders on Sunday, November 8, at Levi's Stadium.
The extra preparation time could help Buckner adjust to the team's current defensive system before his potential return to action. His availability will depend on the completion of the physical examination and any subsequent roster decisions.
The Colts, meanwhile, will continue their season with a younger roster and additional draft resources. Their next personnel decisions will help determine how extensive the organization's restructuring becomes before the trade deadline.
For Buckner, the immediate opportunity is a return to a familiar franchise that is positioned to compete in the NFC. His previous tenure ended with a Super Bowl appearance, and his second stint begins with San Francisco leading its division.
