It turned out to be Sixers guard Danny Green, who now has been officially waived, per the NBA transactions log.
Green, 36, appeared in two games with the Sixers this season, failing to score, after re-signing with the team this past offseason.
He spent last season with the Cavaliers, averaging 6.5 points and shooting 45 percent on 3-pointers in eight games. He also played for the Sixers from 2020-22, as well as served stints with the Raptors, Lakers, Grizzlies and most notably the Spurs.
Green is currently 39th on the all-time NBA 3-point list with 1,577 career-made threes. He is also ninth in career playoff 3-point field goals with 315 made threes in the postseason.
