DaJuan Summers was cut by Montepaschi Siena, according to Sportando (hat tip: I am a GM):
"DaJuan Summers is no longer a player of Montepaschi Siena. Former Detroit Pistons forward did not perform as expected and the Italian reigning champs decided to part ways with him. Summers was averaging 4ppg in 3 Serie A games and 4 points in the only game he has played in Euroleague."
Maybe the Pistons shouldn’t feel bad about rarely playing Summers.
