Jimmer just announced on KSL radio, that he'll be hosting two games in Utah, involving players from the 2011 Draft Class. He confirmed that Tyler Honeycutt and Isaiah Thomas will be joining him, as well as many other Rookies, including Kemba Walker. He will update who will be attending as the date approaches. The games will be take place Wednesday, Sept. 21 and Thursday, Sept. 22.
Both games will be broadcast on KSL Radio, the 2nd game will be broadcast on BYUTV. You can watch BYUTV live online, or on their free iPad/iPhone app. I assume the first game will not be televised.
Here is audio of the announcement.
