Steve Nash ruled out for season with back injury

LOS ANGELES — Los Angeles Lakers guard Steve Nash has been ruled out for the season with a back injury, putting the two-time NBA MVP's career in doubt.

The Lakers and Nash announced their decision Thursday, less than a week before the start of what would have been the 40-year-old Nash's 19th NBA season.

Nash played in just 15 games last season with nerve root irritation, but had high hopes for a comeback after months of rehabilitation.

Instead, the Canadian point guard strained his back while carrying bags several days ago. Nash and the Lakers apparently determined he couldn't return this season.

Nash won two MVP awards with the Phoenix Suns, but he has played in just 65 games since the Lakers traded four draft picks for him in 2012. His contract ends next summer.
