The plan is for him to participate in the Summer League playoffs, a source confirmed. The playoffs portion of the summer league begin on Wednesday. Smith will be taking his physical Tuesday. He is expected to arrive in Las Vegas shortly after that.
Smith is coming off knee surgery that was taken care of in February. If he is able to be cleared and there's still games to be played, Smith will be available for games. For the Mavs, they will play at least two games as that is the minimum that Dallas would play in the playoff portion of the summer league.
The 6-foot-10, 250-pound Smith averaged 5.3 points and 4.1 rebounds in 14.4 minutes per game over the last three seasons with the Houston Rockets. The Bulls signed him through next season after Houston waived him in April.
Chris Haynes of Comcast SportsNet Northwest first reported the story.
