With less than two months until the NBA preseason tips off, the Boston Celtics have become radio nomads.

Entercom Communications announced Tuesday that Celtics games will no longer be carried on their WEEI and WRKO stations after an agreement could not be reached on a new contract. The stations had been the radio home of the Celtics since 2005.

“WEEI has had an incredible run with the Boston Celtics, from being a part of their 17th championship banner to the end of the Big 3 era,” Entercom Boston vice president/market manager Jeff Brown said in a statement.
