Stephen Curry is not playing tonight because he is recovering from a Grade 1 left hamstring strain that he suffered during the playoffs earlier this year. He exited Game 1 due to this injury and has been sidelined for multiple games while being re-evaluated periodically. His team and medical staff do not expect him to play unless he is fully healed and ready, and as of the latest updates, he is still in rehabilitation and has not yet been cleared to return to the court for games that are critical in the playoff series.
