The National Basketball Association has notified teams that regular season games through to Dec. 15 have been canceled because of the labor dispute that has locked out players for nearly five months, a league spokesman said on Tuesday.

The NBA had already scrapped the first month of a regular season that was originally scheduled to begin Nov. 1 and the latest move came a day after players rejected a contract offer that included plans for a shortened season.

Only the first month of the regular season has offically been scrapped but NBA Comissioner David Stern said last week that the 2011-12 campaign would start in mid-December if a deal with players was reached.
