The Celtics have invited guard Dan Dickau to training camp, according to agent Mark Bartelstein.

Dickau played in Germany last season, averaging 17.6 points in just five games for the Brose Baskets.

He played for Boston during the 2005-06 season, but tore his Achilles' tendon and was eventually traded to Portland for Sebastian Telfair.
