The Sixers are depleted up front with Arnett Moultrie undergoing ankle surgery on Thursday and Kwame Brown dealing with a strained right hamstring. Saturday when the team started training camp the Sixers added two players with size to their training camp roster: Solomon Alabi and Nayal “Mac” Koshwal. Alabi (7-foot-1) was originally the 50th overall pick by the Mavericks in the 2010 NBA draft before his rights were traded to the Raptors. The 25-year-old played two seasons for Toronto in 2010-11 and 2011-12. Last season Alabi played for the Idaho Stampede of the NBA Development League and Ikaros Chalkidas of the Greek League. “I am excited to come out here and play” Alabi said. “I see it as an opportunity and I am excited that they invited me to come out here and play. I think I can make this roster. I just have to play hard and work hard every day and stick to the system.”
