The gruesome lower-leg injury that led to Oklahoma City Thunder standout Jalen Williams being taken off the court on a stretcher on Sunday, Oct. 25, will cost him a significant portion, if not all, of the 2026-27 NBA season.
Williams suffered a fractured fibula and dislocated ankle in his left leg, Thunder general manager Sam Presti confirmed in a Monday, Oct. 26, press conference. Presti said the injury will require surgery but did not provide a timeline for Williams' potential return to the team.
Presti called the injury one that's more associated with contact sports like football, but added that he'd been in contact with Williams, who was determined to move forward.
"He's as tough as they come. He's an elite competitor," Presti said. "Even last night, just miraculous in terms of his outlook in the way he's looking forward to attacking this. And, you know, we're going to be with him the entire way."
Of the injury, Presti said, "things could have been a lot worse." Presti evoked past injuries that have cost the team's stars significant time, including Williams battling multiple injuries last season and Chet Holmgren losing his rookie season to a foot injury.
Presti said "he hadn't given a lot of thought" to any roster moves in response to the loss of a key player this early in the season. Williams is a career 17.9 point-per-game player who made the NBA All-Star Game in his last healthy season in 2024-25.
Presti also gave an update on fourth-year guard Cason Wallace, who suffered a left labral tear in his shoulder that will require surgery and sideline one of the Thunder's top defenders for an undetermined amount of time.
Wallace was attempting to fight through a screen early in the Oct. 25 game when he grabbed his shoulder area in pain and was escorted off the court.
Wallace finished eighth in Defensive Player of the Year voting in the 2025-26 season.
According to the Cleveland Clinic, this type of tear can take up to six to 12 months of recovery following surgery.
Oklahoma City will be short-handed for their game against Phoenix Suns Monday at Paycom Center. While Williams and Wallace are out indefinitely, Chet Holmgren (right patellar tendinitis) is also sitting out the home game.
The absence of Holmgren could be precautionary, considering it’s the second night of a back-to-back stretch for the Thunder. He missed all five of the Thunder’s preseason games due in part to a quad contusion.
Phoenix Suns coach Jordan Ott addressed Williams' injury before his team took the court against the Thunder Monday night, telling reporters he and his staff saw the play because they were watching the game and scouting the team they were playing next.
"Feel for any athlete that's worked their way back, and tried to stay healthy ... Just unfortunate news, but this is sports," Ott said. "Got to go out and play, play the next game. We know that they'll bring a lot of energy to this one. We gotta match it." — Duane Rankin, Arizona Republic
How Jalen Williams broke his fibula, dislocated his ankle
Williams' injury occurred after an awkward landing under the basket with 1:14 left in the fourth quarter in the Thunder's 108-101 home victory over the Clippers.
Williams went up for a dunk at the 1:15 mark in the fourth quarter and was fouled by Clippers guard Kris Dunn, who came in hard from behind while Derrick Jones Jr. was guarding Williams underneath.
Williams' left foot rolled under his leg upon landing, and it was immediately clear that he had suffered a significant injury. A team official was seen coming over to place a towel over Williams' leg as he was quickly attended to by an athletic trainer, while Thunder stars Shai Gilgeous-Alexander and Holmgren reacted in shock nearby.
The tone in Paycom Center immediately changed in the arena as members of both teams began to turn away, while Thunder players could be seen getting emotional over the scene.
The crowd was heard chanting "JDub" before the 25-year-old All-Star was carted off the court on a stretcher. He was seen giving two thumbs up to the fans in the arena.
Known as a versatile two-way player, Williams won a championship with the Thunder in 2025 and was named to the All-NBA third team and the All-Defensive second team for the 2024-25 season. Williams is one of Oklahoma City's premier ball handlers and offensive engines, and he is often the primary creator when two-time and defending NBA MVP Shai Gilgeous-Alexander is on the bench.
"I just feel bad for him," Gilgeous-Alexander said, while fighting tears in his postgame interview. "... We just got to hold the fort down until he comes back."
Thunder coach Mark Daigneault was asked for the status of injured players, including Williams, after the game. Daigneault said that Williams' injury "speaks for itself."
“Those are tough, man," Daigneault said when talking about the feeling in the locker room. "We're not doing great.”
The coach thanked the fans for their support of Williams and chanting his name after the injury.
“I think anybody that's in the arena can empathize with that," Daigneault said. "So appreciate our fans for doing so.”
The fibula is the smaller bone in the lower leg, and a fracture of that bone is considered less serious than a break to the larger tibia, which supports the body's weight. According to the Cleveland Clinic, recovery from a fibula fracture can vary depending on the type of break, but often involves recovery of six to eight weeks for the bone to heal completely, followed by a period of physical therapy.
Fibula fractures don't typically cause long-term complications and usually heal faster than other leg fractures because the fibula doesn't support your weight when you stand and move.
The fibula fracture sounds bad, but the ankle dislocation could be more concerning for Williams' future. According to Cleveland Clinic, the dislocation could "take several months or longer to heal," and people who dislocate a joint are more likely to dislocate it again in the future. Williams will likely need to wear a protective brace throughout his playing career to reduce risk of future dislocation.
While certainly not something Thunder coaches, executives, players and staff are paying attention to, the betting markets also took notice of the major injuries to Williams and Wallace – both of whom will require surgery and extended time off.
As of the evening of Monday, Oct. 26, the Thunder's 2027 NBA championship odds lengthened to +347 from +238 on Oct. 24, per BetFinder’s consensus. In implied probability – the likelihood of winning suggested by betting odds – Oklahoma City fell 7.2 percentage points from 29.6% to 22.4%. That’s the largest peak-to-trough decline of any NBA team in BetFinder data dating to July 7.
That shift dropped Oklahoma City behind San Antonio, which became the new championship favorite at +288.
