The Pelicans have been without reserve center Alexis Ajinca all season and that isn’t likely to change for the rest of the year. As Christian Boutwell of the New Orleans Advocate writes, the 29-year-old underwent knee surgery on his right patellar tendon and is expected to miss four-to-six months. While the news may not come as a surprise to the franchise, it’s an added blow to a team that’s struggled to keep their big men healthy. Last season Ajinca averaged 5.3 points and 4.5 rebounds per game but that’s of little help when he can’t stay on the floor.
