LeBron James misses season start with sciatica; Warriors and Lakers adjust with injuries and new players.

The Golden State Warriors and Los Angeles Lakers open the 2025 NBA season without LeBron James, sidelined for up to a month with sciatica. Stephen Curry, 37, leads the Warriors, who are managing injuries and aging roster concerns while relying on Jimmy Butler, Draymond Green, and new signings including Al Horford, Deandre Ayton, Marcus Smart, and Jake LaRavia. Luka Doncic, in his first full season with the Lakers after a trade from Dallas, is expected to carry a heavy load alongside Austin Reaves, with the team aiming to rebound after a first-round playoff exit. Both teams seek strong starts amid roster changes and health challenges.
