NBA notes: Phoenix Suns fire general manager Ryan McDonough

In the final week before the regular season, teams are usually shoring up rotations, making final roster decisions and readying for the 82-game season.

The Phoenix Suns took a bolder step on Monday — they canned their general manager.

Ryan McDonough, whom the team hired from Boston in 2013, will be replaced on an interim basis by former NBA player James Jones and Trevor Bukstein. Both men were in Phoenix’s front office under McDonough.

The Suns finished with fewer than 25 wins in each of the last three seasons.

Spurs’ Murray tears ACL

San Antonio, already facing a big challenge as the Spurs fully transition out of the Tim Duncan-Tony Parker-Manu Ginobili era, got dealt a huge blow Monday when results showed starting point guard Dejounte Murray suffered a torn anterior cruciate ligament in his right knee.

Murray, one of the preseason favorites to contend for the most improved player this season, just turned 21 before heading into his third pro season.

The Spurs lost rookie guard Lonnie Walker IV for a few months after he tore the meniscus in his right knee last weekend.

Patty Mills or Derrick White likely will have to become a starter for the Spurs, as their bid to return to the playoffs gets tougher before the season even starts.
