Johnny Cardoso's debut season at Atlético de Madrid has officially come to a premature end—and it's been a tough one to watch. The American midfielder suffered a high ankle sprain during a routine rondo drill in training on Thursday, after taking a heavy challenge from a teammate. Tests confirmed the injury, marking his fifth setback of the season and ruling him out for the final four LaLiga matches.

This latest blow couldn't come at a worse time. With Atlético eliminated from the UEFA Champions League at the semifinal stage midweek, the team's focus shifts solely to domestic play. But for Cardoso, the bigger concern is his spot on the USMNT roster for the upcoming FIFA World Cup. The 24-year-old had just started to regain the trust of head coach Mauricio Pochettino, working his way back into the national team picture after a frustrating year. Now, his availability for the June 12 opener against Paraguay in Los Angeles is in serious doubt.

Let's put this season in perspective. Cardoso arrived at Atlético from Real Betis as a key summer signing, fresh off helping his former club reach the UEFA Europa Conference League final. But he came in carrying an ankle injury from the Gold Cup—a stubborn issue that never fully went away. That injury set the tone for a campaign plagued by fitness problems, a stark contrast to his previous three seasons where he missed just 21 games combined. This year alone, he's been sidelined repeatedly, making only 30 appearances across all competitions and just 15 in LaLiga.

There was a glimmer of hope in early 2026. Between February 21 and March 22, Cardoso started seven of eight matches, finally getting the consistent run many had expected when he was brought in to challenge veteran Koke for a starting role. He even scored his first goal for the club during the Champions League playoff tie against Club Brugge, showing flashes of the midfielder who had generated so much excitement. But just as he was building momentum, this latest injury has stopped him cold.

For Atlético, it's another frustrating chapter in a season where injuries have disrupted the squad's depth. For Cardoso, it's a painful reminder of how quickly fortunes can change in football. As he begins his recovery, the countdown to the World Cup will feel especially urgent. Whether he can get fit in time remains to be seen, but one thing is clear: this has been a season of what-ifs for a player who seemed destined for so much more.
