This is not White's first stint in the D-League.  Last year he spent 16 games with the Rio Grande Vipers and averaged 11.4 points, 5.7 rebounds and 3.3 assists in 25.6 minutes a game.

This doesn't affect Orlando Johnson, who signed a 10-day contract last Wednesday.  According to Larry Coon's CBA FAQ:

White's 10-day contract will expire as the Kings end their road trip, meaning if he does well in Reno, his next 10-day would be during Sacramento's 4 game home stand.  The Bighorns have six games in the next ten days so there will be plenty of opportunity for Royce to prove himself.  All D-League games are available to watch for free on Youtube, so check out the Bighorns schedule if you're interested.
