Celtics News: Boston reportedly acquires Pelicans' Austin Rivers in Jeff Green trade

Update: 7:24pm EST 1/10/15

The Boston Herald cites a source indicating that Rivers is unlikely to head to Boston, despite Stein's report.

"The bottom line is that the Celtics don't need another guard," the source said.

Per the Herald's source, the Celtics could very well pick up a different piece in the deal, even if Rivers is shipped somewhere else in the trade agreement.

"This deal is a continuously changing thing," the source said. "More names could still be added to it before it's over."

The Memphis Grizzlies and Boston Celtics reportedly agreed to terms to a trade on Friday that will ship Jeff Green to Memphis in exchange for Tayshaun Prince and a 2019 first-round pick from the Grizzlies.

However, the deal was said to be waiting on a third team to join the fray, and it appears the New Orleans Pelicans have entered the mix and added another piece to Boston's haul.

ESPN sources say New Orleans is poised to join Memphis/Boston deal for Jeff Green ... with Austin Rivers going to Celts

Remains to be seen if deal is pushed through today or if it waits until league office opens Monday. But the three teams have agreed to terms

To close out the deal, the Pelicans would acquire Quincy Pondexter from Memphis.

The 22-year-old Rivers is the son of former Celtics' head coach Doc Rivers. Picked 10th overall by the Grizzlies in the 2012 NBA Draft, the youngster has yet to find his stride. He's averaging just 6.8 points and 2.5 assists per game on 38.7 percent shooting from the field in 2014-15, and will be an unrestricted free agent at season's end.
