K League 1 fixtures October 2026 - the next eight matches and what each one decides

Fifty-one K League 1 matches are still to be played, and the next eight of them fall between September 20 and October 10. Only one fixture in that window puts a club currently holding a continental place on the field, and it puts two of them there at once. That is Jeju SK at FC Seoul on October 10. Ulsan HD, who sit second on 47 points, have eight matches left but none of them inside this window. Nor do Gwangju FC at the bottom, who also have eight to come. Everything else in the next eight is a club chasing, a club surviving, or both.

Every figure here is as of the September 20 update. Four fixtures fell on that Sunday. Two are already in the standings quoted below, Jeju winning 1-0 at Gangwon FC and Jeonbuk Hyundai Motors drawing 2-2 with Gwangju. Two had not been played when these numbers were computed, Seoul away at Pohang Steelers and Daejeon Hana Citizen away at Incheon United, so they are counted here as pending rather than decided. A clinch number assumes the worst case throughout, that every rival takes maximum points from everything they have left. Ties count against the club being measured.

Take Jeju at Seoul first. Seoul's two numbers, seven points for a top-three finish and nine for the title, both fall by three with a win over Jeju and by one with a draw. A defeat leaves both untouched and takes a match off the nine they have left to find them in. Rival slips can cut the figures faster, but nothing Jeju do on October 10 can raise them. The other end of the fixture is closer to terminal. Jeju's clinch number is 23 and they have eight matches left. No combination of eight matches lands on exactly 23. Seven wins and a draw is 22, eight wins is 24, and there is nothing in between. So the 23 is a long way of saying eight wins, and the first point Jeju drop ends their own-results route, whether they drop it at Seoul or anywhere else. Their title tragic number is three, and a defeat here makes it two.

Jeonbuk at Daejeon on October 9 is the second fixture that matters more than the rest, because Jeonbuk are the first club outside the three places. They have 44 points, Daejeon have 39. A Daejeon win cuts the five-point gap to two. A Jeonbuk win opens it to eight. A draw leaves it at five with a match gone from each side. Daejeon have played 29 to Jeonbuk's 30, so they hold a match in hand on top of whatever the result is. Neither club has a clinch number, which means no run of their own results guarantees a place, so this match moves tragic numbers and nothing else. Jeonbuk's is eight with eight matches left, so no single defeat can finish them and only losing the lot does. Daejeon's is seven with nine left, which is the worse position of the two: they can be mathematically out with two matches still on their schedule.

Pohang at Incheon, also on October 9, is the only fixture of the next eight between two clubs level on points. Both are on 37. They are level now, but both play at least once before they meet, so the gap they bring to Incheon on the Friday will already have been made elsewhere. What this match settles is who ends the week on top of it. Incheon have played 28 and have ten left, more remaining fixtures than any other club in the league. Pohang have played 29 with nine left. Both carry a safety clinch number of two as of the update, which a single win clears outright, and both play on September 20 first, so both may have spent it before they meet. In continental terms neither is close. Thirty-seven points is nine behind Jeju in third, and their tragic numbers for a top-three finish are seven for Pohang and eight for Incheon.

Gangwon appear twice in the next eight, at home to Incheon on September 27 and at home to Bucheon FC 1995 on October 9. Gangwon have 42 points from 29 matches with nine to play, and no clinch number at all. That is the point of both fixtures. No combination of Gangwon results guarantees them a continental place, because a perfect finish from them still loses to a perfect finish from enough of the clubs above. Points won here change the gap and nothing else. Their tragic number is eight of the nine, so the door only shuts on something close to a total collapse. Incheon arrive five points behind with a match in hand, which is the meeting of the club with the most fixtures left and the club with no way to settle anything itself. Bucheon arrive with a safety clinch number of seven: a win takes three of those seven and leaves four, a draw leaves six.

FC Anyang at Gimcheon Sangmu on October 10 is the smallest fixture in the window and the easiest to read. Anyang are on 38 with a safety clinch number of one, so a single point anywhere across their eight matches makes them mathematically safe. Gimcheon are on 33 and need six, so a win leaves three. Five points separate the two clubs, and one point separates Gimcheon from Bucheon below them. The two pending fixtures on September 20 share a number: Pohang at home to Seoul and Incheon at home to Daejeon both carry a home safety figure of two, so a home win in either clears it on the spot. Pohang also carry a title tragic number of one, which a defeat to Seoul would spend, and Daejeon are already safe at zero.

After September 20, one fixture sits on September 27, Incheon at Gangwon, and then five cluster across October 9 and 10. The order inside that weekend is the thing to watch. Jeonbuk at Daejeon, Pohang at Incheon and Bucheon at Gangwon all go on the Friday, so Seoul and Jeju both know exactly what the chasing clubs did before they kick off on the Saturday. Ulsan are worth one eye while that happens: second on 47 with eight to play, they carry a clinch number of 22 and a title tragic number of four. The live table refreshes as results land and the full remaining schedule is at. To put your own results into these fixtures and watch the figures move, use.

How to read these numbers. A clinch number is the smallest further return, counted in league points, that guarantees an outcome even if every rival takes maximum points from here. A tragic number is the count of further defeats after which the outcome becomes impossible even if the club wins everything else. Zero means it is already decided, and no number at all means the club's own results cannot get there whatever they are. Ties are counted against the club being measured, so a clinch here will sometimes trail an official announcement by a day. The continental and relegation rules are on the postseason page, and each club has its own figures, for example Seoul at and Jeju at.
