David Mirkovic Undergoes Foot Surgery: What It Means for Illinois Basketball in 2026-27

For weeks now, every conversation surrounding Illinois basketball seemed to circle back to David Mirkovic.

Whether it was Brad Underwood, an assistant coach, or a teammate, the message rarely changed. Mirkovic had transformed his body. He had taken another step in the weight room. He looked more explosive. More physical. More comfortable as the player Illinois expected to build around this season.

Now, that excitement has been put on pause. Illinois announced Tuesday that Mirkovic underwent successful surgery on his left foot after suffering an injury during a team workout on July 31. The surgery was performed in Indianapolis, and while the program expects him to make a full recovery, it did not provide a timetable for his return.

It’s unfortunate timing for a player who appeared poised to make the leap from All-Big Ten caliber player to legitimate All-American candidate.

The Buzz around Mirkovic’s summer

David Mirkovic was already one of the nation’s most productive freshmen last season, averaging 13.3 points, 8.0 rebounds and 2.6 assists while shooting 48.4 percent from the field and 37.5 percent from beyond the arc. His versatility helped power Illinois to the Final Four, and everything coming out of Champaign suggested an even bigger sophomore campaign was on the horizon.

Perhaps the biggest indication of Mirkovic’s commitment came this summer. Rather than spending the offseason with his national team, Mirkovic elected to stay in Champaign. The goal was simple: continue reshaping his body, improve his conditioning and prepare for what everyone inside the program believed could be a special season.

That decision made the injury even more heartbreaking. After sacrificing the opportunity to represent his country to invest in his development at Illinois, David Mirkovic suffered an injury just weeks before preseason practices ramp up.

Fortunately for Illinois, this isn’t last year’s roster. One of the biggest strengths of this team is its depth. The Illini have far more lineup flexibility than they’ve had in recent seasons, and that should soften the blow while Mirkovic works his way back.

Who steps up?

The most logical move would be sliding Jake Davis into the starting lineup alongside Stefan Vaaks, Quentin Coleman, Tomislav Ivisic and Andrej Stojakovic.

Davis has proven he’s capable of filling multiple roles. He understands Underwood’s system, defends with toughness, rebounds his position and doesn’t need the offense built around him to impact winning. While he can’t fully replicate Mirkovic’s unique blend of playmaking and interior versatility, he gives Illinois an experienced, dependable option that allows everyone else to remain in their natural roles.

This could also create opportunities for Ethan Brown or Lincoln Williams to carve out meaningful minutes sooner than expected if Illinois wants to play a smaller lineup. Both freshmen have earned praise for their versatility and could provide a different look off the bench. Another possibility is expanding Zvonimir Ivisic’s role, allowing the 7-footer to absorb more frontcourt minutes while Tomislav Ivisic slides into different matchups. Illinois has several options, and the Illini’s depth gives Underwood the flexibility to mix and match until Mirkovic is ready to return.

None of those options replace Mirkovic. Players with his combination of size, skill and playmaking simply don’t grow on trees.

The Illini schedule

The good news is the calendar. Illinois still has roughly three months before opening the season against Fairleigh Dickinson, and the program expects Mirkovic to make a full recovery.

The challenge is what comes next. Illinois won’t have much time to ease into the season. Underwood has assembled one of the toughest nonconference schedules in the country, and the Illini will be tested almost immediately. That’s why getting Mirkovic back as close to full strength as possible is so important. Lower-extremity injuries—especially foot injuries—can linger, and even after a player is cleared, it often takes time to regain conditioning, confidence and timing.

Illinois has the depth to survive if David Mirkovic misses games early. That’s exactly why Underwood built this roster the way he did.

But to reach the lofty goals this team has set for itself, Illinois will eventually need the version of Mirkovic that coaches and teammates spent all summer raving about.

If, and when that player returns, the Illini will once again have one of the highest ceilings in college basketball.
