On Sunday night, the website draftexpress.com tweeted that Syracuse University sophomore Fab Melo had signed with an agent.

"Fab Melo has signed with Arn Tellem, according to multiple sources, which means he obviously isn't returning to Syracuse, as expected.''

However, a source familiar with the negotiations said the deal was not final and might not be for a week.

"Will he sign with Arn? Probably,'' the source said. "Is it a lock? No.''

In either case, Melo has made the decision to leave Syracuse and enter the NBA draft. A second source who is close to Melo said the 7-foot center would not return to Syracuse next season.

The source said that Melo left the SU campus last Thursday to make a short visit with his family in Brazil. The source said Melo is expected back in Syracuse this week.

Melo averaged 7.8 points and 5.8 rebounds for Syracuse (34-3) this past season. He also blocked 88 shots to lead the Big East in blocks per game. He was named the Big East's Defensive Player of the Year.

However, Melo missed three games in late January due to an academic issue. He was reinstated. But just before the start of the NCAA Tournament, he was ruled ineligible again. He missed all of SU's games in the NCAA Tournament. The Orange still advanced to the Elite Eight before losing to Ohio State.

Melo is currently rated as a late-first or early-second round draft pick. Draftexpress has him going to the Toronto Raptors with the fourth pick in the second round. The mock draft at nbadraft.net predicts that the Oklahoma City Thunder will take Melo with the 29th overall pick, the next-to-last pick in the first round.

Tellem represents some of the NBA's top players, including Derrick Rose, Russell Westbrook, Pau Gasol and LaMarcus Aldridge. But Tellem's agency, the Wasserman Media Group, has a bevy of clients, including former Syracuse player Rick Jackson, who spent the 2011-12 season playing for a professional team in France.
