Warriors’ Richardson undergoes surgery

The surgery cleaned out debris caused by normal wear and tear. He is expected to be ready for the start of the season.

In 75 games last season, all starts, Richardson averaged 23.2 points, 5.8 rebounds and 3.1 assists.

Richardson, 25, is one of only five players in NBA history to increase his scoring average in each of his first four NBA seasons following his rookie campaign, joining Karl Malone, Stephon Marbury, Billy Cunningham and Jack Twyman.
