The 28-year-old played 25 minutes during Wednesday's overtime loss to the Phoenix Suns.
This is a difficult setback for Clarkson, who has been largely durable for much of his career. While he appeared in only 59 contests in 2014-15, he still managed to earn first-team All-Rookie honors while on the Los Angeles Lakers.
Clarkson averaged a then-career-best 16.8 points to go with 3.3 rebounds and 2.4 assists per game in 2018-19 for the Cleveland Cavaliers and finished the 2019-20 campaign with 15.2 points and 2.6 rebounds per night for Cleveland and Utah, which acquired him via trade.
He is an important part of the Jazz's backcourt rotation because he is versatile enough to handle point guard duties but also play on the wing as someone who can shoot three-pointers and penetrate the lane. His presence as a spark off the bench is a major reason Utah is among the league's best teams.
He helped lead the club to the playoffs last season and has responded with 17.2 points and 3.9 rebounds through 51 games in 2020-21.
Look for the Jazz to turn to a combination of backcourt options until he returns.
Mike Conley and Donovan Mitchell can both handle the ball, while Bojan Bogdanovic, Joe Ingles and Royce O'Neale provide depth on the wing.
