Kevin Garnett has informed the Celtics that he will return to the team for his 18th NBA season.

According to two sources, Garnett and the Celtics are working on a three-year, $34 million deal.

“The decision came down to whether KG wanted to keep playing,” said one source. “And once he decided that he did, it was going to be Boston. He wasn’t going to leave Doc (River) and those guys and play anywhere else.”
