The NBA locked out its players Friday when its collective bargaining agreement expired, becoming the second pro sports league shut down by labor strife.
The labor deal ended at midnight after players and owners failed to reach a new contract. The two sides remained far apart on just about every major issue, from salaries to the salary cap, revenues to revenue sharing.
The long-expected lockout puts the 2011-12 season in jeopardy and comes as the NFL is trying to end its own work stoppage that began in March.
It is believed to be only the second time that two leagues have been shut down simultaneously by labor problems.
