The sky is falling in Chicago. Ten games into the season, the Bulls are just 1-9 while looking uncompetitive in most contests, and their worst-case scenario has come to pass.

No. 4 overall pick Caleb Wilson, whose athleticism and playmaking on both sides of the ball have been among the few bright spots for the Bulls this season, will miss four to six weeks with a fractured right hand. The rookie forward suffered the injury during a 124-119 loss to the San Antonio Spurs on Wednesday.

Will Chicago be tenable without Wilson? Who needs to step up in his absence? How will head coach Tiago Splitter adjust his lineups? All are questions that will be answered in the coming month:

Wilson's arrival in Chicago was supposed to make things easier for Buzelis in his third NBA season. With Wilson slotting in at the '4,' Buzelis would slide up a position and likely take advantage of being matched up against smaller wings.

Instead, the 22-year-old has taken a back seat in the Bulls' offense. Buzelis is taking roughly three less shots per game than he did a year ago and is averaging 13.5 points per game on just 43.9% efficiency (31.4% from three.) He's also turning the ball over a career-high 2.8 times per game, more than any Bull except Josh Giddey.

So much of the Bulls' offense runs through Wilson, and Buzelis has ended up in the corner on many possessions. Buzelis hasn't been able to capitalize on the looks that Wilson's gravity has earned him, but with Wilson sidelined, perhaps Buzelis can find some offensive rhythm out of necessity.

Buzelis needs to fit alongside Wilson if he wants to remain an integral part of Chicago's future, not the other way around. What he does in the next four to six weeks won't change that, but it might be able to build up his confidence for when Wilson does return to the court.

Jalen Smith has started all nine games for the Bulls this year, and the expectation was that he would move to the bench once Nic Claxton's conditioning became good enough. Smith's shooting and ability to space the floor have benefited Chicago's offense while he averages 12.8 points and 7.4 rebounds per game on 53.3% shooting.

Smith has proven to play better when he's next to a true center, and with Wilson sidelined, he now has the perfect opportunity to do so. Claxton is already making an impact — he finished with 17 points, six rebounds and a block on 5-of-6 shooting in Wednesday's game — and could enter the Bulls' starting lineup soon. Wilson and Smith have been arguably the two best scorers on the team so far this season, and moving Smith to the bench may prove detrimental for the league's worst shooting offense.

The other candidate would be Isaac Okoro, who has started the past two games while Norman Powell heals from back spasms. Okoro's defense has drawn the praise of Tiago Splitter and a starting backcourt of him, Giddey and Powell would move Buzelis back to the '4,' where he mostly played last year.

On Wednesday night against the Spurs, the Bulls were already collapsing when Wilson left the game. But everything got significantly worse without the rookie forward.

San Antonio went on a 57-41 run from the time Wilson exited to the final 20 seconds, when Chicago added some late garbage-time baskets to make it a five-point margin. The second half was ugly, as the Bulls turned the ball over 12 times, resulting in 16 fastbreak points and 16 points off turnovers. Chicago was also outscored in the paint, 38-22.

It's clear that the Bulls' offense and defense already revolve around the 20-year-old, who is able to create his own shot, rebounds well, is an adept passer, finds himself in defensive passing lanes and is a menacing shot-blocker at the rim. Without someone who does all of that — and in many cases, was one of the few reasons the Bulls have been in these games — will everything fall apart?

This season was meant to evaluate how certain pieces fit around Wilson ahead of a long-term rebuild. Without the team's centerpiece, we could be in for some rough basketball ahead.
