Six-time NBA All-Star Blake Griffin has agreed to a contract buyout with the Detroit Pistons and will become an unrestricted free agent, sources tell ESPN.

The Brooklyn Nets, Golden State Warriors, Miami Heat and Portland Trail Blazers are expected to be among the teams Griffin will be considering for his next stop, sources tell ESPN.

Griffin, 31, is expected to make a decision on his next team after conversations with prospective teams, sources said.

Finding a trade for Griffin -- who was owed a remaining $36.6 million this season, and $39 million in 2021-22 prior to the buyout -- was an insurmountable challenge for the Pistons. Detroit finalized a reduction in his remaining salary to gain free agency with Griffin's agent, Sam Goldfeder of Excel Sports, since the sides mutually agreed he would leave the active roster on Feb. 15 awaiting a trade or a buyout.

Detroit has entered a full-fledged rebuild under first-year general manager Troy Weaver, and the opportunity to play the franchise's younger players has taken precedence for the Pistons.

Injuries have dramatically altered Griffin's game, eliminating the high-flying rim attacks that marked his All-Star career. He's averaging 12.3 points, 5.2 rebounds and 3.9 assists for Detroit this season.

Griffin was traded less than a season into a five-year, $171 million max deal with the LA Clippers, arriving in Detroit in late January 2018.
