The Colts trade Quenton Nelson to the Seattle Seahawks and DeForest Buckner back to the San Francisco 49ers in two separate deals on Tuesday, October 27, 2026, remaking Indianapolis in a single day and strengthening two NFC West contenders at once. Nelson, an eight-time Pro Bowl guard, goes to Seattle for a 2027 third-round draft pick and a 2028 fifth-round pick. Buckner, a three-time Pro Bowl defensive tackle, returns to the team that drafted him for a 2027 fourth-round pick. The Colts, who sit at 2-5 after three straight losses, get future draft capital for two veterans in the final year of their contracts. The Seahawks and 49ers get proven starters for a playoff push.
It is a striking pair of moves because of who is leaving, not just where they are going. Nelson and Buckner were cornerstones of the Colts’ lines for years. Trading both on the same day, two weeks before the November 10 trade deadline, signals that Indianapolis is looking beyond this season.
Why the Colts trade Quenton Nelson now
Nelson, 30, has spent his entire career with Indianapolis since the Colts selected him sixth overall out of Notre Dame in the 2018 NFL Draft. He was a first-team All-Pro in each of his first three seasons, has been selected to the Pro Bowl eight times, and has started all seven Colts games this season. He is in the final season of a four-year, $80 million contract, so trading him now lets Indianapolis collect draft picks rather than risk losing him in free agency with nothing in return. Reuters reported the Seattle deal is pending a physical exam.
Seattle, the defending Super Bowl champions at 4-3, gets a lineman built for exactly what it needs. The Seahawks are coming off a win over Kansas City, but their ground game has struggled to find consistency this season, and USA Today noted that Seattle quarterback Sam Darnold was sacked five times in the two games before that win. Nelson should stabilize the interior of the line in both pass protection and the running game.
Nelson spoke before the trade about what Indianapolis has meant to him, saying, in comments reported by USA Today: “I love it here, I met my wife here, I really appreciate and love this organization. It’s been a long career here, made a lot of friendships and bonds here that I don’t take for granted.”
The timing also follows a change at the top in Indianapolis. The Colts fired general manager Chris Ballard, who drafted Nelson, on October 19, with interim general manager Ed Dodds now overseeing personnel decisions. Indianapolis had already given up future first-round picks in an earlier deal for cornerback Sauce Gardner, which makes the new draft capital from Tuesday’s trades especially valuable for a rebuild.
Buckner returns to San Francisco
Hours after the Nelson deal, Buckner was headed back to where his career began. The 49ers selected the 32-year-old seventh overall out of Oregon in the 2016 NFL Draft, and he played his first four seasons in San Francisco before the Colts acquired him in 2020 for a first-round pick. The Colts confirmed Tuesday that they acquired a 2027 fourth-round pick from San Francisco in exchange for Buckner.
With Indianapolis, Buckner earned first-team All-Pro honors in 2020 and Pro Bowl selections in 2021 and 2023. The Colts said he totaled 47 sacks, 122 quarterback hits and 63 tackles for loss in 95 games with the team. He has 75.5 sacks in his career, including four through seven games this season after returning from season-ending neck surgery, and his four sacks this season are more than any 49ers player has recorded, according to Reuters.
San Francisco, at 6-1, needs him for a different reason: injuries. The 49ers’ defensive line has played much of the season without end Nick Bosa, who has a calf injury, and several other linemen. Buckner, in the final year of his contract and set to become an unrestricted free agent after the season, gives them an experienced interior pass rusher for the stretch run. The 49ers are on their bye this week and return on November 8 against the Las Vegas Raiders.
Buckner had not hidden his frustration after Indianapolis lost 16-10 at Minnesota on Sunday, its third straight defeat. Asked about the team’s struggles, he said, as reported by Reuters: “I don’t know. How about you guess. I’m frustrated. Same thing. We lost.”
Analysis: what Tuesday changes for all three teams
This is a clearly labeled analysis section, not a report of a new result. For Indianapolis, the logic is cold but clear: two expiring contracts became three future draft picks, and a 2-5 team with a new interim general manager now has more flexibility to reshape its roster. The cost is real, though. Nelson and Buckner were not just productive players; they were the kind of veterans a young locker room leans on. A rebuild that trades away its standard-bearers has to replace that leadership, not just the snaps.
For Seattle, the bet is that a great guard can still change a season in November. If Nelson steadies the run game and keeps Darnold cleaner, the Seahawks’ ceiling rises without giving up a first-round pick. For San Francisco, the bet is narrower and just as sensible: a proven pass rusher, returning to a familiar team, on a defensive line that has been held together by depth players. Neither acquiring team had to mortgage its future to get better now, which is why both deals make sense even at a modest draft-pick price.
The question that follows is whether Indianapolis is finished. With the trade deadline still two weeks away on November 10, other veterans on expiring deals could draw calls. Tuesday’s message, at least, was unmistakable: the Colts are sellers, and the NFC West is buying.
What to watch next
Watch for the official completion of the Nelson deal once the physical is done, and for how quickly both players are worked into their new teams. Seattle will want Nelson in the lineup as soon as possible, while San Francisco has the bye week to get Buckner ready for November 8. Also watch Indianapolis ahead of the November 10 deadline: if the Colts make another move, it will confirm that Tuesday was the start of a larger reset rather than a one-day clear-out.
