Bulls Release Summer League Roster, Waive Spencer Dinwiddie

(CBS) Point guard Spencer Dinwiddie's time in Chicago didn't last long.

After acquiring Dinwiddie in a trade with the Pistons in June, the Bulls waived him Thursday, according to reports. He was working on a non-guaranteed contract.

The Bulls have also released their Summer League roster, which opens play in Las Vegas on Saturday.

Four players -- Jerian Grant, Bobby Portis, Cristiano Felicio and Denzel Valentine -- are under contract and figure into Chicago's plans for the upcoming season. The rest will be looking to impress and achieve the long shot of grabbing a final roster spot, as Felicio did last season for the Bulls.

Here's a look at the roster.

Rasheed Sulaimon, G, Maryland (R)
Jerian Grant, G, Notre Dame (1)
Bobby Portis, F, Arkansas (1)
