 Welcome back, everyone. Former UConn star Stephon Castle is being shut down for the rest of the NBA Summer League in Vegas. The San Antonio Spurs rookie point guard suffered a right wrist sprain in last week's game against Donovan Klingin and the Portland Trailblazers. The fourth overall pick in last month's draft was having a good summer so far, averaging over 17 points, nearly six rebounds and four assists per game. He should be fine come the regular season.
