The Celtics created five new trade exceptions after sending out Dennis Schroder, Enes Freedom, Bruno Fernando, P.J. Dozier and Bol Bol in deals on Thursday, according to a league source. Trade exceptions are valid for one year and they allow teams to acquire players without sending out matching salary in return. The Celtics used the $9.7 million exception that they created by trading Tristan Thompson to the Kings last summer in order to acquire Daniel Theis from the Rockets, the source said. That exception was set to expire this summer.
