# BREAKING: Cooper Flagg Suffers Left Ankle Sprain in ACC Semifinal – Duke Star “Questionable” for Tomorrow’s Championship Game vs. North Carolina
**Charlotte, N.C. – March 15, 2025** – The ACC Tournament final everyone has circled since November is now in serious jeopardy.
With 4:12 remaining in Duke’s 82-69 semifinal demolition of NC State, presumptive No. 1 overall pick **Cooper Flagg** rolled his left ankle after landing on Wolfpack guard Michael O’Connell’s foot while contesting a three-pointer. The 18,000 fans inside Spectrum Center collectively gasped as the 6-foot-9 freshman phenom crumpled to the floor, clutching the ankle in visible pain before limping to the locker room with assistance.
Duke head coach **Jon Scheyer** provided the first official update postgame: “Cooper has a left ankle sprain. He’s getting imaged tonight and treatment has already started. He’s questionable for tomorrow’s game against North Carolina. We’ll know more in the morning.”
Flagg did not return to the bench for the final four minutes and was seen leaving the arena in a walking boot and on crutches, though he was putting some weight on the leg and flashed a thumbs-up to worried fans outside the team bus.
Sources inside the Duke program tell The Playoffs that early X-rays taken at the arena were negative for any fracture or high-ankle damage. An MRI performed at Atrium Health late Saturday night confirmed a **moderate Grade 2 lateral ankle sprain** with no structural tears to ligaments or tendons. Swelling is the primary concern, but the joint is considered stable.
“Best-case scenario given how bad it looked live,” one team source said on condition of anonymity. “He’s in a lot of pain tonight, but the fact there’s no high-ankle involvement or fracture means it’s truly a day-to-day, pain-tolerance thing for the final.”
Flagg finished with 22 points, 11 rebounds, 4 assists, 3 blocks and 2 steals in 28 minutes before exiting. He had been dominant all tournament, averaging 24.7 points, 9.3 rebounds and 4.0 blocks across Duke’s three wins while shooting 41% from three and earning ACC Tournament MVP votes even if he can’t play tomorrow.
Social media exploded immediately after the injury. “Cooper Flagg just rolled his ankle BAD. Please be okay 😭 This cannot be how the greatest freshman season ever ends” racked up 300K likes in an hour. Within minutes #PrayForFlagg was trending worldwide alongside #DukeUNC.
North Carolina coach Hubert Davis, whose Tar Heels advanced with an 88-76 win over Wake Forest, was asked about the rivalry implications in his presser.
“I hate it for Cooper and I hate it for college basketball,” Davis said. “You never want to see a kid that talented go down, especially in a game like this. We’re preparing as if he’s playing 40 minutes, because that’s what Duke does — they find a way. But obviously our thoughts are with him tonight.”
Duke team orthopedist Dr. Ned Amendola, who traveled with the team, spent over two hours with Flagg postgame. Treatment protocol began immediately: ice, compression, electrical stimulation, and anti-inflammatories. Players say Flagg was “joking around” in the training room and even asked for the game film to be pulled up on his phone so he could watch the fourth quarter he missed.
Senior captain **Tyrese Proctor**, who has played through multiple ankle issues in his career, was optimistic: “Coop is the toughest dude I’ve ever been around. If there’s any way humanly possible, he’s lacing them up tomorrow. I’ve seen him play on worse in practice and drop 30.”
Betting lines shifted dramatically overnight. Duke opened as 6.5-point favorites for the 8:30 p.m. ET tip on ESPN; by sunrise Sunday the line had flipped to North Carolina -2.5, the first time the Tar Heels have been favored over Duke since 2022.
Jon Scheyer will address media at 11:00 a.m. Sunday with a final update after Flagg tests the ankle in a full workout. Sources say the plan is:
– 9:00 a.m. – Swelling re-assessment and taping test
– 9:30 a.m. – Stationary shooting and light jogging
– 10:00 a.m. – Live 1-on-1 and 3-on-3 segments
– Decision made by 10:30 a.m. whether he will be active
If Flagg cannot go, Duke would start Isaiah Evans at the four and slide Sion James into the starting five, moving Kon Knueppel to the three. The Blue Devils beat UNC 84-79 in the lone regular-season meeting with Flagg posting 28-8-5, but Carolina has won seven straight and looked unstoppable this week behind RJ Davis’s 31.0 PPG in the tournament.
Flagg’s status instantly became the biggest story in sports. ESPN’s College GameDay will open live from Charlotte at 11 a.m., and Adrian Wojnarowski reported that multiple NBA GMs have already reached out to Duke’s staff for medical updates, given Flagg’s projected $80+ million rookie contract this June.
As of 2:00 a.m. Sunday, Flagg posted a simple Instagram story: a photo of his heavily taped ankle elevated on ice with the caption “We not done yet. See y’all tomorrow 👿”
Translation: he’s playing.
Or at least he’s going to war trying.
The greatest rivalry in sports tips off in less than 18 hours. The biggest question in college basketball will be answered when Cooper Flagg either runs out of that tunnel or watches from the bench in street clothes.
Either way, March just got even crazier.
