Eh, it sounds like he put in his notice and then they told him not to come in. That's pretty shitty though. Doesn't sound like he has anything lined up. They just booted him out. Radio is ruthless like that. There one day, gone the next.
It's funny, when he was out last week they had Wheels on with Sheldon, and Wheels walked all over Sheldon. Treated him like a total noob. Cut him off and basically took over the show. They were interviewing the radio guy for the Warriors, asking about Ezeli, and Wheels just made Sheldon look weak.
