ANALYSIS: This would be devastating news for the Warriors if Thompson's injury keeps him out of the lineup for an extended period. Klay was just feeling healthy again after taking a full year off to recover from a torn ACL that he suffered in the 2019 Finals.

Expect updates on Klay's status going forward.
