Kevin Garnett will return to the Boston Celtics after agreeing to a three-year contract Saturday, according to multiple reports.

The Celtics star will earn $34 million with the new deal, Yahoo!Sports and the Boston Herald reported.

"The decision came down to whether KG wanted to keep playing," a source closed to the negotiations told the Herald. "And once he decided that he did, it was going to be Boston. He wasn't going to leave Doc (Rivers) and those guys and play anywhere else."

Garnett, 36, earned $21 million last season with the Celtics as he averaged 15.8 points and 8.2 rebounds in helping them reach the Eastern Conference finals. He averaged 19.2 points and 10.3 rebounds in the playoffs.

The 17-year veteran was considering retirement after this season. However, he seemed rejuvenated this season when coach Doc Rivers moved him from power forward to center.

With the free-agent negotiating period beginning Sunday, the Celtics' next pressing need is deciding whether to bring back guard Ray Allan and forward Brandon Bass.
