General manager Bob Myers announced Monday the center will miss all of training camp, per Slater.
Cauley-Stein fought the injury bug throughout 2017-18 with the Sacramento Kings while still posting career-highs with 12.8 points, seven rebounds and 2.4 assists per game. He played through injury as much as he could, but a lower back injury caused him to miss time in December and March.
The 2015 No. 6 overall pick has brought momentum from his breakout year into last season—his final in a four-year tenure with the Kings—as he averaged 11.9 points, 8.4 rebounds, 2.4 assists and 1.2 steals across 81 starts.
Expectations were high for the 26-year-old this season after signing a two-year, $4.4 million contract with the Warriors in free agency, but the latest injury could delay his debut.
Should Golden State be without Cauley-Stein, head coach Steve Kerr will likely turn to Kevon Looney at center.
