Grizzlies' Darrell Arthur out for season

MEMPHIS, Tenn. -- Memphis Grizzlies forward Darrell Arthur has had season-ending surgery to repair a torn right Achilles tendon.

The team announced Friday that Arthur is expected to be ready for the 2012-13 season. He suffered the injury Dec. 18.

Arthur averaged 9.1 points and shot about 50 percent last season, his third in the NBA.

Meanwhile, the Grizzlies waived forward Walter Sharpe, who had signed Dec. 10. He last played for Detroit during the 2008-09 season.
