Pelle, 27, is 6-foot-10 and appeared in 20 games with the Philadelphian 76ers last season, averaging 2.1 points and 3.0 rebounds.
Pelle was eligible for the NBA draft in 2014 but did not get drafted. He is of Antiguan/Lebanese descent and has spent the majority of his pro career either overseas or with Delaware of the G League.
The Cleveland Cavaliers signed Pelle to an Exhibit 10 contract last month, presumably so he could join the Canton Charge. But joining the Nets would clearly upstage heading to the G League bubble.
Pelle proved to be an accomplished protector of the paint with the Delaware Blue Coats last season, averaging almost 3.0 blocked shots per game.
Assuming Pelle signs, the Nets will still have two open roster spots. At least one will need to be filled by next weekend.
