The Sixers on Tuesday announced their roster which will compete in the 2012 Orlando Pro Summer League. The five-day event will take place from July 9-13.

Maurice Harkless, the 15th overall selection in the 2012 draft, headlines the Sixers' squad. Harkless was named Big East Rookie of the Year this past season after averaging 15.5 points, 8.6 rebounds and 1.5 assists per game for St. John's.

Arnett Moultrie, who was acquired by the Sixers from the Miami Heat in last week's draft, suffered a sprained ankle last month during a pre-draft workout and will not participate (see story).

Some names you may be familiar with on the summer roster include: Nik Vucevic, Zack Rosen, John Scheyer and Jacob Pullen.

Vucevic played 51 games for the Sixers last season. He averaged 5.5 points and 4.8 rebounds per game in his rookie campaign.

Rosen went undrafted in last week's draft after averaging 18.2 points, 5.2 assists and 3.2 rebounds per game last year for Penn.

Former Duke product Scheyer spent last season with Maccabi Tel Aviv in Israel. He went undrafted in 2010 after helping Duke to a national title that same year.

Pullen averaged 16 points and 3.2 assists per game last season for Angelico Biella in Italy. He went undrafted out of Kansas State in 2011.
