Detroit president of basketball operations Trajan Langdon said Monday that Thompson (illness) will be limited to open training camp, Omari Sankofa II of the Detroit Free Press reports.

Langdon said Thompson has been cleared for conditioning, strength training and non-contact drills, but the forward is still going through a medical process with the NBA's Players Association. Thompson's rookie season was cut short in March after undergoing treatment for a blood clot, and understandably, the Pistons and the NBA are taking every precaution. Expect more updates as the preseason progresses.
