Purdue basketball’s second-round NCAA tournament game against Miami turned anxious on Sunday when sophomore guard C.J. Cox went down with an apparent right knee injury early in the second half. What had been a competitive, back-and-forth game in St. Louis suddenly had a much heavier storyline running alongside the score.
Cox had been one of the most energetic players on the floor before the injury, and his exit raised immediate questions about how the Boilermakers would manage the rest of the game and potentially beyond, depending on the severity of what happened to his knee.
How the injury happened
With 17:04 left in the second half and Purdue holding a narrow 45-42 lead, Cox pushed the ball up the floor on a fastbreak and drove toward the basket. As he went up for the layup and absorbed contact from a pair of Miami defenders, his right knee appeared to buckle underneath him. He was fouled on the play, but that hardly registered in the moment.
Cox went down immediately beneath the basket and stayed on the floor for several moments. CBS microphones picked up his reaction, which left little doubt about the pain he was in. Purdue’s training staff came onto the court to assist him, and after a tense pause, Cox was helped to his feet. Encouragingly, he was able to walk toward the tunnel and into the locker room largely under his own power, which offered some initial relief to his teammates and coaching staff watching from the sideline.
The injury update and what followed
CBS sideline reporter Jon Rothstein reported that Cox had been listed as questionable to return and was running lightly inside the locker room to test whether the knee could hold up for further play. It was a hopeful sign that he was moving at all, though the outcome remained uncertain for much of that stretch.
With 7:38 remaining in the game, Rothstein provided an update that Cox had made his way back to the Purdue bench. A subsequent shot on the CBS broadcast showed him seated with his teammates, visibly working through his right leg in an effort to gauge what was possible. He had not returned to the court at that point, but his presence on the bench at least suggested the situation had not worsened dramatically.
What Cox contributed before going down
The injury arrived at a particularly difficult moment for Purdue because Cox had been playing some of his best basketball of the game right before it happened. He finished with 11 points on 4-of-5 shooting at the time he exited, including a stretch in the final minutes of the first half that kept the Boilermakers very much in the contest.
During a span of just one minute and 37 seconds late in the first half, Cox connected on three consecutive 3-pointers, a burst of scoring that helped pull Purdue back within two points of Miami heading into the break. Without that run, the deficit at halftime could have been far more difficult to overcome.
Why Cox matters so much to Purdue
Cox has been a two-year starter for the Boilermakers and one of the steadier contributors in head coach Matt Painter’s rotation throughout the season. Coming into Sunday’s game, he was averaging 8.4 points per game on 44.8% shooting from the field and 37.4% from 3-point range. He ranked third on the team with 58 made 3-pointers on the year, making him a critical part of how Purdue stretches opposing defenses and creates spacing for drives and post touches.
Losing a perimeter shooter of his caliber even temporarily in the flow of a tournament game removes a meaningful piece of what makes Purdue’s offense functional. The full extent of the injury was not immediately confirmed during the broadcast, and the Boilermakers were left navigating the second half of a high-stakes March Madness game while hoping for better news from the locker room about one of their own.
